Question

factorise the following 4 x square + 24 x + 20​

Answer 1

4x^2 + 24x + 20

=x^2 + 6x +5

=x^2 + 5x + x + 5

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

=x+1 or x+5

therefore

x=-1 or x=-5

Answer 2

Step-by-step explanation:

$take \: 4 \: common \: in \: the \: gien \: eq \\ {x}^{2} + 6x + 5 \\ {x}^{2} + 5x + x + 5 \\ x(x + 5) + 1(x + 5) \\( x + 1)(x + 5) \\ take \: x + 1 = 0 \: \: and \: x + 5 = 0 \\ x = - 1 \: \: and \: x = - 5 \\ hence \: the \: value \: of \: x = - 1 \: and \: - 5$
