Question

A quadratic in factored form is given as (x + 5) (2x - 3) = 0, what are the solutions of this given equation?

X = and x =

Answer 1

Explanation:

Answer 2

x = -5, x = 1.5

Explanation:

If the two expressions multiplied together is 0, that means that one of the expressions would have to equal 0. This gives us two possible answers. Our two equations are now:

x + 5 = 0

2x - 3 = 0

We will first solve the first one!

To isolate x, we subtract 5 from both sides to get:

x = -5

Onto the second one!

We begin to isolate x by adding 3 to both sides.

2x = 3

Now we divide both sides by 2.

x = 3/2 or 1.5
