Question

factorise : 5√5x^2+30x+8√5 by middle term splitting

Answer 1

$solution \\ 5 \sqrt{5} {x}^{2} + 30x + 8 \sqrt{5} \\ = 5 \sqrt{5} {x}^{2} + 20x + 10x + 8 \sqrt{5} \\ = 5x( \sqrt{5} x + 4) + 2 \sqrt{5} ( \sqrt{5} x + 4) \\ = (5x + 2 \sqrt{5} )( \sqrt{5} x + 4) \\ = 5x + 2 \sqrt{5} = 0 \: and \: \sqrt{5} x + 4 = 0 \\ = x = \frac{ - 2}{ \sqrt{5} } \: and \: x = \frac{ - 4}{ \sqrt{5} }$
