Question

how to solve this question​

Answer 1

Answer:

$x {}^{2} - 4x - 4$

Step-by-step explanation:

the sum of zeroes

I.e.,

$\alpha + \beta = 4$

the product of zeroes

I.e.,

$\alpha \times \beta = ( - 4)$

now

$x {}^{2} - ( \alpha + \beta )x + \alpha \times \beta$

$x {}^{2} - 4x + ( - 4)$

I.e.,

x^2 - 4x - 4
