Answer:
-1
Step-by-step explanation:
x = 5 and -2
Given the function of x to be;
f(x) = (x-5)(x+2)/x+1
The value of x that will make the function zero can be calculated for by equating the given function to zero first to have;
If f(x) = 0, then;
(x-5)(x+2)/x+1 = 0
Cross multiplying;
(x-5)(x+2) = 0
(x-5) = 0 and x+2 = 0
x = 5 and x = -2
The value of x that will make the function zero is therefore 5 and -2
x = 2
4x+5x-9=15+x
We are going to collect like terms
9x-9=15+x
exact answer 91/4 the mixed fraction is 23 3/4 and then
23+1/2+1/4=23 3/4
