    Can I ask a question? In number 3, my answer is 2x² + 6x - x + 3 since in a foil method First is 2x is multiplied by x is 2x², Outer is 2x × 3 is 6x, Inner is -1 multiplied by x my answer is x because the variable (x) is always 1 and Last is -1 × 3 is -3. And then there is similar terms, you add it which is 6x and x and my answer is still 6 (I don't know if I am right, you can correct me if I'm wrong). My final answer is 2x² + 6x - 3. (Based on my understanding, in multiplication of integers unlike sign is equals to always negative). So why is your answer is different? Am I wrong? I'm sorry I don't get it Sir.

  • @chantsang255
    @chantsang255 Před rokem +13

    I have questions . 15:24 number 4 why is that it became x or 1 as the b instead of 3x?
    This is how I solve it , I used the FOIL METHOD
    (3x+6) (x-1) =0
    First ; 3x multiple to x = 3x^2
    Inner ; 3x multiple to 1 = 3x
    Outer; 6 multiply to x = 6x
    Last ; 6 multiple to 1 = 6
    So we have 3x^2 + 3x + 6x + 6
    3x & 6x same sign so it will be equaled to = 9x
    So we now have 3x^2 + 9x + 6 =0
    ( you can notice the gcf is 3 so we divide it all by 3 )
    3 divide by 3 = 1 or X
    3 divided by 9 = 3
    3 divide by 6 = 2
    So shouldn’t the answer be
    X^2 + 3x + 2 = 0
    How did it became x^2+x-2=0? Genuinely asking also why is it negative when
    + 6 and -1 is the one we solved , 6 is the greater number shouldn’t we copy the greater number’s sign ? Thank you to anyone who’d answer where did I get wrong or maybe it was a small mistake by the teacher 😁

      @jaceyrielle3511 you're gonna add the like terms 4x + 5x = 9x if the equation is ONLY asking you to ADD you'll add the numbers as if the variable 'x' don't exist.. you add 4+5=9 and add 'x' that's a rule in adding with variable.. you said that you get the answer '9x²'.. you'll only get this kind of answer ONLY if you MULTIPLY.. for example:
      3x time 4x = 12x² that's also a rule in multiplying numbers with the same variable.. I hope this help. Tell me if you need clarification. Have a nice day!❤

    • @angelsapirasaydoquen4123
      @angelsapirasaydoquen4123 Před rokem +2

      By using the FOIL method (you can search this up if you don't know what this is), the solution will look like this:
      (2x^2 - 1)(x + 3)
      = 2x^2 + 6x - x - 3
      = 2x^2 + 5x - 3
      You probably overlooked the 6x - x, or perhaps you have forgotten that 6x - x = 5.

      #4
      Here's the explanation
      (3x+6)(x-1) = 0
      Applying the FOIL Method
      3x² - 3x + 6x - 6 = 0
      Combine similar terns -3x and 6x
      3x² + 3x - 6 = 0
      since the coefficients 3, 3 and -6 are divisible by 3, so we have to make them relatively prime by dividing 3.
      Thus, the equation becomes
      x² + x - 2 = 0 and a = 1, b = 1 and c = -2.

    • @XerMarFernandez
      @XerMarFernandez Před 2 lety +7

      #5
      Here's the explanation 1.
      3x(x-2)=15
      3x(x-2) is just one term and so 3 is the gcf of 3x(x-2) and 15. By dividing the gcf 3, the equation becomes x(x-2)=5. Apply distributive property, we have now x²-2x=5. Apply Subtraction Property of Equality,
      x² - 2x - 5 = 5 - 5
      Thus the final equation is
      x²-2x-5=0 where a=1, b=-2 and c=5.

    • @XerMarFernandez
      @XerMarFernandez Před 2 lety +4

      #5
      Explanation 2
      3x(x-2)=15
      Apply Distributive Property
      3x²-6x=15
      Apply SPE
      3x²-6x-15=15-15
      3x²-6x-15=0
      Now the coefficients 3, -6 and -15 are divisible by 3 and 3 is their gcf. We'll divide the terms by 3 to make the coefficients relatively prime.
      The final equation is x²-2x-5=0 where a=1, b=-2 and c=-5.
