Question

factorise x^r+5x+4
plz give me the answer ​

Answer 1

✔Factorizing by middle split term:-

${x}^{2} + 5x + 4 = 0$

$\implies {x}^{2} + 4x + x + 4 = 0$

$\implies \: x(x + 4) + 1(x + 4) = 0$

$\implies(x + 4)(x + 1) = 0$

$\implies(x + 4) = 0 \:or \:(x + 1) = 0$

$\implies \: x = - 4 \: \: or \: \: x = - 1$

plz mark me as brain list ✔.
