Question

If (x-2) and (x plus 3) are factors of p (x) is equal to ax ka Cube + 3 x square - BX - 12 find the value of a and b​

Answer 1

Step-by-step explanation:

ax^3+3x^2-Bx-12 is the equation

x=2,-3 are the zeroes

then substitute in equation

at x=2

8a+12-2B-12=0------(1)

B=4a----[1]

x= -3

-27a+27+3B-12------(2)

substitute [1] in (2)

-27a+15+12a=0

15a=15

a=1

then B =4
