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

  • Alg 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.
