Question

Solve for x. Write the smaller solution first, and the larger solution second. (x -4)(-5x +1)=0

Answer 1

Answer: smaller x= 1/5

Larger x=4

Explanation:

Answer 2

The product of the two is 0, so one of them have to equal 0 as any number multiplied by 0 is 0.

First solution: x - 4 = 0

If x - 4 = 0, then x = 4. So the first solution for x is 4.

Second Solution: -5x + 1 = 0

Solving...

-5x + 1 = 0

-5x = -1

x = -1/-5

x = 1/5 or 0.2

So x = 0.2 and 4
