Question

3
Find the remainders when
x4+ 4x² - 5x²-6x +7 divided
by
x-3​

Answer 1

I hope this point is clear .

Answer 2

${\huge{\boxed{\mathcal{\red{Answer}}}}}$

Given Polynomial f(x) = x⁴ + 4x³ - 5x³ - 6x + 7 is divided by x - 3 then remainder is f (3).

x - 3 = 0

x - 3 = 0 x = + 3.

$f (3) = (3)⁴ + 4(3)³ - 5(3)² - 6(3) + 7$

$= 81 + 4 (27) - 5(9) - 18 + 7$

$= 81 + 108 - 45 - 18 + 7$

$= 196 - 63$

$= 133.$

Hope It'll Helps!
