Question

solve the quadratic equations by factorisation method x^+6x+5=0​

Answer 1

Explanation:

x² + 5x + x + 5 = 0

x(x+5) + 1(x+5) = 0

(x+5) (x+1) = 0

(i) x+5 = 0

x = -5

(ii) x+1 = 0

x = -1

Answer 2

Answer:

x = -1 & -5

Explanation

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