Question

factorise : 5 root5x^2 +30x +8 root 5

Answer 1

Step-by-step explanation:

$5 \sqrt{5} {x}^{2} + 30x + 8 \sqrt{5} \\ = 5 \sqrt{5} {x}^{2} + 20x + 10x+ 8 \sqrt{5} \\ = 5x( \sqrt{5} x + 4) + 2 \sqrt{5} ( \sqrt{5} x + 4) \\ = ( \sqrt{5} x + 4)(5x + 2 \sqrt{5} ) \: are \: \\ required \: factors \: of \: given \: \\ algebraic \: expression.$
