  1. (x+10)(x+10)=(x+10)^2
  2. (x-3)(x+12)=x^ ​2 ​+12x−3x−36=x^2+9x−36
  3. (x+4)(x-3)=x^2+x−12
  4. (x+5)(x+2)=x^2 ​​+7x+10
  5. (x-3)(x-4)=x^ ​2 ​​−4x−3x+12=x^2(-4x-3x)+12=x^2-7x+12
  6. (x+8)(x-8)=x^2-64 used difference of squares
  7. (x-6)(x+3)=x^2+3x−6x−18=x^2+(3x−6x)−18=x^2-3x-18
  8. (x+1)(x-5)=x^2−5x+x−5=x^2(−5x+x)−5=x^2-4x-5

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

Answer:

Explanation:

Please, no more than 2 problems per post!

8: (x + 10)(x + 10) = (x + 10)^2. This is the "square of a binomial." There's a formula for this: (a + b)^2 = a^2 + 2ab + b^2, so the final answer here is:

x^2 + 20x + 100

13. (X + 8)(x-8) is a "special product," and the product is the difference of two squares: (X + 8)(x-8) = x^2 + 8x - 8x - 64 = x^2 - 64
