Question

find the roots of the equation using factorisation method x²+5x_6=0​

Answer 1

Step-by-step explanation:

${x}^{2} + 5x - 6 \\ = {x}^{2} + 6x - x - 6 \\ = x(x + 6) - 1(x + 6) \\ = (x + 6 )(x - 1) \\ (x + 6) = 0 \: \: \: (x - 1) = 0 \\ x = - 6 \: \: \: \: x = 1 \\ \\ \\ \\ roots \: of \: eqn \:are \: x = - 6 \: or \: 1$
