Question

X+1 is the factor of 2x³+ax²+2bx+1 given that 2a-3b=4 find the value of a and b

Answer 1

Answer:

b=2 a=5

Step-by-step explanation:

x +1 = 0

x=-1

substitute x = -1

2x³+ax²+2bx+1=0

then u get

a-2b=1-------(1)

given

2a -3b=4---------(2)

multiply (1) with 2

solve the eq (1) and (2)

then  we get b=2 a=5

hope it helped u
