Question

Solve the given quadratic equation by factorisation method, $x^{2} + 15 x + 50 = 0$

Open in App

Solution

The given quadratic equation $x^{2} + 15 x + 50 = 0$ can be factorised as follows:

$x^{2} + 15 x + 50 = 0 \Rightarrow x^{2} + 10 x + 5 x + 50 = 0 \Rightarrow x (x + 10) + 5 (x + 10) = 0 \Rightarrow (x + 5) = 0, (x + 10) = 0 \Rightarrow x = - 5, x = - 10$

Hence, $x = - 5$ or. $x = - 10$
