Divide (28x5 + 29x4 + 5x3 + 86x2 + 56x + 53) by (–4x – 7) using synthetic division.
bixtya [17]

Answer:

 -7x⁴+5x³-10x²-4x-7 - 4/4x+7

Step-by-step explanation:

Given the division problem, (28x⁵ + 29x⁴ + 5x³ + 86x² + 56x + 53) by (–4x – 7), find the solution in the attachment below.

The polynomial of a function is expressed as P(x) = Q(x) + R(x)/D(x)

Q(x) is the quotient

R(x) is the remainder

D(x) is the divisor

Accordin gto the divsion, Q(x) = -7x⁴+5x³-10x²-4x-7

R(x) = 4

D(x) = -4x-7

Substituting this functions in the polynomial P(x);

P(x) =  -7x⁴+5x³-10x²-4x-7 - 4/4x+7
