Question

2x^4-3x^3+5x^2-4x-3 divided by x+2

Answer 1

Answer:

Step-by-step explanation:

x+2=0

x=-2

Substitute x=-2in the equation

2x4-3x³+5x²-4x-3

=2(16)+3(8)+5(4)+8-3

=32+24+20+8-3

=32+24+20+5

=81

Hope u will understand............

Answer 2

Answer:

Step-by-step explanation:

The zero of the polynomial x - a is given by

x + 2 = 0

So

x = - 2

Let f(x) = 2x⁴ - 3x³+ 5x²-4x - 3

Now by the Remainder Theorem the required Remainder is

f(-2)

= 2(-2)⁴ - 3(-2)³+ 5(-2)²-4(-2) - 3

= 32 + 24 + 20+8 - 3

= 81
