Question

1. Find the roots of X^2-root5x-30=0​

Answer 1

Answer:

➡Here's your answer

${x}^{2} - \sqrt{5} x - 30 = 0 \\ \\ {x}^{2} - 2 \sqrt{5} x + 3 \sqrt{5x} - 30 = 0 \\ \\ x(x - 2 \sqrt{5} ) + 3 \sqrt{5} (x - 2 \sqrt{5} ) = 0 \\ \\ (x - 2 \sqrt{5} )( x + 3 \sqrt{5} ) = 0 \\ \\ roots \: are$

$x = + 2 \sqrt{5} \: and \: - 3 \sqrt{5}$

Hope it helps ✌
