select the two values of x that are roots of this equation.
2x - 3 = -5x2

x = -1    or  x =

Step-by-step explanation:

2x - 3 = -5x²

This is a quadratic form of equation.

We will start by rearranging the equation, we will move all the variable to the left-hand side of the equation, which means the right-hand side of the equation will become zero.

Add 5x² to both-side of the equation

2x - 3 +  5x² =   -5x² + 5x²

2x - 3  + 5x²  =  0

5x² + 2x -3 = 0

Now we can now proceed to solve;

Find two factors such that it sum will give  5 and its product will give -15

The two numbers are 5 and -3 (That is 5×-3 = -15 and 5 +(-3)=2)

We will replace 2x  by 5x and -3x

So that our equation becomes;

5x² + 5x -3x-3 = 0

We will now factorize

( 5x² + 5x) (-3x -3 )= 0

On the first bracket, 5x is common and so it  will be factored out and on the second bracket -3 is common and so it will be factored out

5x(x + 1) -3(x + 1) = 0

(x+1)(5x-3) = 0

Either x +1 = 0            ⇒    x = -1

or

5x - 3 = 0              

5x = 3

x =
