25 If x^2-x-6=0 then x= ?
Factor:
(x___)(x___)=0
Fill the blanks with two integers that multiply to give you c=-6 and add together to give you b=-1.
-3*2=-6 and -3+2=-1
(x-3)(x+2)=0
Set each parentheses = to 0 and solve for x.
x-3=0 or x+2=0
x-3+3=0+3 or x+2-2=0-2
highlight%28x=3%29 or highlight%28x=-2%29
Happy Calculating!!!!
