Question

Find the remainder when P(x) = 3x³-7x+5 is divided by x+3, (a) Remainder 55 (b) Remainder-55 (c) Remainder 35 (d) none of these​

Answer 1

Answer:

-55

Step-by-step explanation:

factor = x + 3

then, we should take -3

P(x) = 3x³-7x+5

P(-3)= 3(-3)³-7(-3)+5

       = 3(-27) + 21 + 5

       = -81 + 26

    R = -55
