Find the value of a such that (x+a) is a factor of polynomial f(x) =x^4 - a^2 x^2 +2xa+3pls its urgent​

Answer»

Step-by-step EXPLANATION:

SINCE, (X + a) is a FACTOR of F(x), so,

f( - a) = 0

= > ( - a)^{4} - a^{2} ( - a)^{2} + 2( - a)a + 3 = 0

= > {a}^{4} - {a}^{4} - 2 {a}^{2} + 3 = 0

= > {a}^{2} = \frac{3}{2}

= > a = \sqrt{ \frac{3}{2} }
