Question

find quotient and remainder when 2x^2 + 11x - 21 is divided by x+7 Also verify division algorithm​

Answer 1

Step-by-step explanation:

the remainder when equation, p(x) is divided by x+7 is

p(-4)=2×4^2+11×(-4)-21=32-44-21=-33

2x^2+11x-21

2x^2+14x-3x-21

2x(x+7)-3(x+7) = (2x-3)(x+7)

quotient when divided by x+7 is 2x-3
