Solve x^2-8x-9=0 using the x method

x=9,-1

Step-by-step explanation:

First, we are gonna start out with finding two numbers that multiply to equal -9 and add up to equal -8

Those numbers would be -9 & 1

-9+1=-8

-9x1=-9

Now we have

(x-9)(x+1)

x-9=0   x+1=0

  +9 +9   -1  -1

x=-9      x=-1

x=1,--9

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero x=1,--9
