Question

17. 2x2 + ax-a² = 0​

Answer 1

Answer:

$x = \frac{a}{2} \:Or \:x=-a$

Step-by-step explanation:

2x²+ax-a²=0

/* Splitting the middle term, we get

=> 2x²-ax+2ax-a² =0

=> x(2x-a)+a(2x-a) = 0

=> (2x-a)(x+a)=0

=> 2x-a = 0 Or x+a=0

$\implies 2x = a \:Or \:x+a=0$

$\implies x = \frac{a}{2} \:Or \:x=-a$

Therefore,

$x = \frac{a}{2} \:Or \:x=-a$
