2x2-5x-3=0

Two solutions were found :

x = -1/2 = -0.500

x = 3

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(2x2 - 5x) - 3 = 0

Step 2 :

Trying to factor by splitting the middle term

2.1 Factoring 2x2-5x-3

The first term is, 2x2 its coefficient is 2 .
The middle term is, -5x its coefficient is -5 .
The last term, "the constant", is -3

Step-1 : Multiply the coefficient of the first term by the constant 2 • -3 = -6

Step-2 : Find two factors of -6 whose sum equals the coefficient of the middle term, which is -5 .
