Equation Solver:
Let's solve the quadratic
equation:
2x^2+7x = 5
First we need to put the
equation in the form:
ax^2 + bx + c = 0
For
this, we set the equation to equal 0, and arrange the terms
from the highest exponent to the lowest:
2x^2+7x-5
= 0
We have:
a=2 b=7 c=-5
We can now
apply the quadratic formula:
x = ( -b ± √(b²-4ac) )
/ 2a
We find two solutions:
x=0.60849528301415
or x=-4.1084952830142
