Question

What are the solutions of (x - 3)(2x + 4) = 0

Answer 1

x = 3 & x = -2

Explanation:

(x-3) = 0 so x = 3

(2x+4) = 0 so 2x = -4 x = -2

Answer 2

Explanation:

(x - 3 ) (2x + 4) = 0

Either

x - 3 = 0

Therefore x = 3

Or.,

2x + 4 = 0

2x = - 4

x = - 4 /2

Therefore x = -2

Now the value of x is 3 or - 2.
