Question

1. solve yhe quadratic equation 2x²+ax -a² = 0 by factorisation​

Answer 1

Answer:

x = -a and x = a/2

Step-by-step explanation:

2x^2 + ax - a^2 = 0

=> 2x^2 + 2ax - ax - a^2 = 0

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

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

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

=> x = -a and 2x = a

=> x = -a and x = a/2

Hence, x = -a and x= a/2.

Answer 2

there fore the factors are x =a/2,-a
