Question

is (x+1) is a factor of 4x^3+7x^2-2x-5 or not​

Answer 1

ǫᴜᴇsᴛɪᴏɴ :-

Is (x + 1) is a factor of 4x³ + 7x²- 2x - 5 or not ?

Aɴsᴡᴇʀ :-

x + 1 = 0

x = -1

p(x) = 4x³ + 7x²- 2x - 5

p (-1) = 4(-1)³ + 7(-1)² -2(-1) - 5

p(-1) = 4(-1) + 7(1) -2(-1) - 5

p(-1) = -4 + 7 + 2 - 5

p(-1) = 9 - 9

p(-1) = 0

yes, (x + 1) is a factor of 4x³ + 7x²- 2x - 5
