SOLUTION: Solve. 7x + x(x-3) = 0 Also, find the x-intercepts of f(x) = 7x + x(x+3) a. what are the solutions? b. what are the x-intercepts?

Question 132220: Solve. 7x + x(x-3) = 0
Also, find the x-intercepts of f(x) = 7x + x(x+3)
a. what are the solutions?
b. what are the x-intercepts?
Answer by edjones(8007) (Show Source): You can put this solution on YOUR website!
The solutions ARE the x intercepts (when y (or f(x)) equals 0.
7x + x(x-3) = 0
7x+x^2-3x=0
x^2+4x=0
x(x+4)=0
x=0, x=-4
.
7x + x(x+3)=0
7x+x^2+3x=0
x^2+10x=0
x=0, x=-10
.
