Solve the following quadratic equation by factorization:
$2x^2\ +\ ax\ –\ a^2\ =\ 0$
Given:
Given quadratic equation is $2x^2\ +\ ax\ –\ a^2\ =\ 0$.
To do:
We have to solve the given quadratic equation by factorization.
Solution:
$2x^2+ax-a^2=0$
$2x^2+2ax-ax-a^2=0$
$2x(x+a)-a(x+a)=0$
$(2x-a)(x+a)=0$
$2x-a=0$ or $x+a=0$
$2x=a$ or $x=-a$
$x=\frac{a}{2}$ or $x=-a$
The roots of the given quadratic equation are $\frac{a}{2}$ and $-a$.
