Question

Someone please help ASAP


a(x) = 7x^2+4x-5,
and b(x) = x - 4

Answer 1

7x + 32 and 123

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

`(7x^2+4x-5)/(x-4)` = x + 32 +
`(123)/(x-4)`
