Answer 2

Answer:

$\huge\purple\star\underline\mathfrak\pink{ANSWER :-}\purple\star$

Step-by-step explanation:

$f(x) = {2x}^{4} - 13 {x}^{2}$

is divisible by :-

$(x - 2)(x - 1)$

Therefore :-

$f(2) = 2 {(2)}^{4} - 13 {(2)}^{2} + a(2) + b= 0$

$= > 2 a+ b = 20$

........(i)

And,

$f(1) = 2 {(1)}^{4} - 13 {(1)}^{2} + a+ b = 0$

$= > a + b = 11$

........(ii)

On solving both eq. we get

a = 9 and b = 2
