Question

Help on trinomials?

Answer 1

Factor each trinomial. Then match the polynomial (term) on the left with its factored form (definition) on the right.



Match Term Definition
_____ x2 – 8x – 20 A) (x – 5)(x + 4)
_____ x2 + 8x – 20 B) (x – 10)(x + 2)
_____ x2 – x – 20 C) Prime
_____ x2 – 9x – 20 D) (x – 2)(x + 10)

Answer 2

(x+a)(x+b) =x^2 +(a+b)x +ab

Answer 3

(x – 2)(x + 10) =x^2+(-2+10)x -20

Answer 4

isn't b the last one?

Answer 5

B) is the first one

Answer 6

how?

Answer 7

As (x-10)(x+2)=\[(x-10)(x) + (x-10)(2) \\= {x}^2-10x + 2x-20 \\= {x^2}-8x-20\]
