Does anyone know an easy simple way to estimate fractions?

Yea go to Youtµbe University

Step-by-step explanation:

Rewrite to help us solve.

( x - 5 )( 2x + 1 )( x - 7 ) = 0

Since these are all factored out it's easy to solve. We need to set each equal to 0 to find x.

x - 5 = 0                  2x + 1 = 0               x - 7 = 0

x = 5                        2x = - 1                   x = 7

                                x = -

So x - , 5 or 7

x also cannot be a negative number, but can be 0.
