Question

I'm doing quadratic equations x^2 +bx+c =0.I'm supposed to factor each polynomial. I know how to questions like x^2 +8x +12 =0 but this one says, j^2-9jk-10k^2. I'm confused

Answer 1

j^2-9jk-10k^2

what adds to 9, multiplies to 10: 10,1

(j-10k)(j+k)

your teacher is just too easy.

Answer 2

I'm in the ninth grade and not the smartest community
