Question

Solve the equation...
(x-1)(5x+2)=0

Answer 1

solve for x

Answer 2

x=1 and x=-2/5

Answer 3

That is what I thought, but how did you come up with -2/5?

Answer 4

You have an equation of the form \(a \cdot b=0\).

To solve it, break it up into: \(a=0\) or \(b=0\). Then solve each of these separately.

Answer 5

2x+5=0
hence
2x=-5 and
x=-5/2

Answer 6

its other way

Answer 7

5x+2=0
5x=-2
x=-2/5

Answer 8
