Question

if x+2a is a factor of x5-4a2x3+2x+2a+3 find a​

Answer 1

Question:

If x+2a is a factor of x^5 - 4a^2x^3 + 2x + 2a + 3 find a.

To Find:

• Value of a

Solution:

x + 2a = 0

=> x = - 2a

So we get,

x = -2a

Now set in:-

→ ( -2a )^5 - 4. a^2 .( -2a )^3 + 2 ( -2a ) + 2a + 3

→ - 32a^5 + 32a^5 - 4a + 2a + 3

→ -4a + 2a + 3

→ - 2a +3

Now,

→ - 2a + 3 =0

→ a = -3/-2 = 3/2

→ value of a is = 3/2
