how do you solve 7x+x (x-4)=0 solution (s)/arex= find the x- intercepts of f(x)=7x+x(-4) what are the x intercepts
1. 7x + x(x-4) = 0,
7x + x^2 - 4x = 0,
x^2 + 3x = 0,
x(x+3) = 0.
x = 0,
x + 3 = 0,
x = -3.
Solution set: X = 0, and X = -3.
2. F(x)= y = 7x - 4x.
To find x-int, let y = 0:
7x - 4x = 0,
3x = 0,
X = 0 = x-int.
To find y-int, let x = 0:
Y = 7*0 - 4*0 = 0 = y-int.
