Question

if p(x) = x²-3x²+2x-4​

Answer 1

$\sf : \implies \: p(x) = {x}^{2} - 3 {x}^{2} + 2x - 4$

$\star \: \tt{FIRST \: \: WE \: \: WILL \: \: PUT \: \: THE \: \: VALUE \: \: OF \: \: X \: \: AS \: \: 1}$

$\sf : \implies \: p(1) = {1}^{2} - 3 \times {1}^{2} + (2 \times 1)- 4 \\ \\ \sf \: p(1) = 1 - 3 + 2 - 4 \\ \\ \sf \: p(1) = 1 - 1 - 4 \\ \\ \sf p(1) = - 4$
