Can someone help me explain how factoring is used to solve quadratic equations? I can't find an explaination anywhere.

  • algebra -

    say for example

    x^2-3x+2 = 0

    factor that left side

    (x-2)(x-1) = 0

    That tells you that if x = 2, the function is zero, because (2-2)=0
    It also tells you that if x = 1, the function is zero. (1-1) = 0
    so the solution is x = 2 or x = 1
