Find the roots of the following quadratic equations by factorisation: √2 x 2 + 7x + 5√2 = 0

Question

Harshit Singh · Answer

Dear Student &radic;2 x^2 + 7x + 5&radic;2=0 Taking LHS, => &radic;2 x^2 + 5x + 2x + 5&radic;2 => x (&radic;2x + 5) + &radic;2(&radic;2x + 5) = (&radic;2x + 5)(x + &radic;2) The roots of this equation, &radic;2 x^2 + 7x + 5&radic;2=0 are the values of x for which (x - 5)(x + 2) = 0 Therefore, &radic;2x + 5 = 0 or x + &radic;2 = 0 => x = -5/&radic;2 or x = -&radic;2 Thanks
