Answer to Problem 6OE

Quadratic Formula

Explanation of Solution

Given:

The equation is :

   3 x 2 −5x=4

Calculation:

The given equation 3 x 2 −5x=4⇒3 x 2 −5x−4=0 is of the type a x 2 +bx+c=0, where a=3 and b=-5, c=-4 .

   b 2 −4ac= (−5) 2 −4(3)(−4)=25+48=73

So, it can be solved by using the Quadratic Formula : x= −b± b 2 −4ac 2a
