4x^2+8x+10=3x^2+x

Solution for 4x^2+8x+10=3x^2+x equation:

4x^2+8x+10=3x^2+x

We move all terms to the left:

4x^2+8x+10-(3x^2+x)=0

We get rid of parentheses

4x^2-3x^2+8x-x+10=0

We add all the numbers together, and all the variables

x^2+7x+10=0

a = 1; b = 7; c = +10;
Δ = b2-4ac
Δ = 72-4·1·10
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-3}{2*1}=\frac{-10}{2}
=-5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+3}{2*1}=\frac{-4}{2}
=-2
