Question

verify whether x^4+2x^3-2x^2+2x-3 is divisible by x^2+2x-3 or not? how can you verify by using factor theorem​

Answer 1

Answer:

Answer:

f(x)=2x^4-ax^3+4×^2-×+2

we will consider 2x+1 as g(x)

now g(x)=0

2×+1 =0

×=-1/2

now 2(-1/2)^4-a(-1/2)^3+4(-1/2)^2-(-1/2)+2

=-1^4-a3/8+4-1/2+2

=4-a3/8+4-1/2+2

=4+4+2-1/2+a3/8

=10-1×4/2×4+a3/8

=10-4/8+a3/8

=10-1/2+a3/8

=20-1+a3/8

=19+a3+8
