Answer:

7x + 32 and 123

Step-by-step explanation:

One way to divide is to use the divisor as a factor in the numerator

Consider the numerator

7x(x - 4) + 28x + 4x - 5

= 7x(x - 4) + 32(x - 4) + 128 - 5

= 7x(x - 4) + 32(x - 4) + 123

quotient = 7x + 32 and remainder = 123

\frac{7x^2+4x-5}{x-4} = x + 32 + \frac{123}{x-4}
