Find the roots of the following quadratic equations by factorisation: x ^2 – 3x – 10 = 0

Question

Harshit Singh · Answer

Dear student Given, x^2 &ndash; 3x &ndash; 10 =0 Taking LHS, =>x^2 - 5x + 2x &ndash; 10 =>x(x - 5) + 2(x - 5) =>(x - 5)(x + 2) The roots of this equation, x^2 &ndash; 3x &ndash; 10 = 0 are the values of x for which (x - 5)(x + 2) = 0 Therefore, x - 5 = 0 or x + 2 = 0 => x = 5 or x = -2 Thanks
