Solve for x. Write the smaller solution first, and the larger solution second.
f(x)=(x-5)(5x+2)
bigX-
SmallX-

  x = -2/5  or  5

Step-by-step explanation:

We assume you want the values of x that make f(x) = 0. These are found using the zero product rule. That tells you a product is zero if and only if at least one factor is zero.

  x -5 = 0 . . . . .assume the first factor is zero

  x = 5 . . . . . . . add 5

__

  5x +2 = 0 . . . assume the second factor is zero

  5x = -2 . . . . . subtract 2

  x = -2/5 . . . . divide by 5

__

smaller solution: x = -2/5

larger solution: x = 5
