Answer:

Let

f(x) = a {x}^{3}  + b {x}^{2}  + x - 6

Given

f( - 2) = 0 \: and \: f(2) = 4 \\  \{ \: x + 2 = 0 \implies \: x =  - 2 \\  \:  \: \: x  - 2 = 0 \implies \: x =   2  \: \}

So

a ({ - 2)}^{3}  + b { (- 2)}^{2}   - 2- 6 = 0 \\  - 8a  +  4b = 8 \\ b - 2a = 2 \:  \: ..... \: eq1 \:  \\  \\ and \\  \\ a {2}^{3}  + b {2}^{2}  + 2 - 6 = 4 \\ 8 a + 4b = 8 \\ 2a + b = 2 \: ......eq \: 2 \\  \\ add \: both \: eq \\  2b = 4 \implies \: b = 2 \\  \\ subtract \:  \\  - 4a = 0 \implies \: a = 0 \\ so \\  \\   \huge\orange{a = 0 \:  \: and \:  \: b = 2}
