Question

iv)x+2
if f(x) = x + 4x² – 3x² - 62 +7 is divisible by x +2​

Answer 1

First solve the equation or make it simpler

4x^2 - 3x^2 = x^2

-62+7 = -55

so the equation now is. x^2 +x -55

Now divide the equation by x+2 through long division method

x^2+x-55

-----------------. = quotient x-1 remainder -53

x+2

your answer will be -53
