Hope it hlpz...

Answer 2

❗❗ Hey Mate ❗❗

Your answer is ---

we have ,

$2 {x}^{2} - 54x - 648$


For roots ,

$2 {x}^{2} - 54x - 648 = 0 \\ \\ = > 2 {x}^{2} + 72x - 18x - 648 = 0 \\ \\ = > 2x(x - 36) - 18( \times - 36) = 0 \\ \\ = > (x - 36)(2x - 18) = 0 \\ \\ = > x = 36 \: or \: \frac{18}{2} = 9$
