2x^2+7x-10=3x-1

Solution for 2x^2+7x-10=3x-1 equation:

2x^2+7x-10=3x-1

We move all terms to the left:

2x^2+7x-10-(3x-1)=0

We get rid of parentheses

2x^2+7x-3x+1-10=0

We add all the numbers together, and all the variables

2x^2+4x-9=0

a = 2; b = 4; c = -9;
Δ = b2-4ac
Δ = 42-4·2·(-9)
Δ = 88
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{88}=\sqrt{4*22}=\sqrt{4}*\sqrt{22}=2\sqrt{22}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-2\sqrt{22}}{2*2}=\frac{-4-2\sqrt{22}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+2\sqrt{22}}{2*2}=\frac{-4+2\sqrt{22}}{4}
