Question

factorise 13x^2+27x+2
​

Answer 1

$= {13x}^{2} + 27x + 2 \\ \\ = {13x}^{2} + 26x + x + 2 \\ \\ = 13x(x + 2) + 1(x + 2) \\ \\ = (13x + 1)(x + 2) \\ \\ x = \frac{ - 1}{13} \: \: \: and \: \: \: x = - 2$

Answer 2

$\sf \underline{Question : - } \\ \\ factorise \: \: \: {13x}^{2} + 27x + 2$

$\sf \underline{Answer : - } \\ \\ = {13x}^{2} + 27x + 2 \\ \\ = {13x}^{2} + 26x + x + 2 \\ \\ = 13x(x + 2) + 1(x + 2) \\ \\ = (13x + 1)(x + 2) \\ \\ (13x + 1)(x + 2) = 0 \\ \\ x = \frac{ - 1}{13} \: \: \: and \: \: \: \: x = - 2$
