Question

Q) Use synthetic division and divide
(4x4+10x3-3x2+2x-21)+(x+3)​

I will mark you brain list

Answer 1

Answer:

It is a factor of dividend

explan:

(4x⁴ +10x³ −3x² +2x −21) ÷ (x+3)

+4 + 10 − 3 + 2 − 21

−3

−12 + 6 − 921

+4 − 2 + 3 − 70

Here the reminder is 0

Hence, (x + 3) is a factor (4x⁴ + 10x³ − 3x² + 2x − 21)
