12x2-7x=10

Solution for 12x2-7x=10 equation:

12x^2-7x=10

We move all terms to the left:

12x^2-7x-(10)=0

a = 12; b = -7; c = -10;
Δ = b2-4ac
Δ = -72-4·12·(-10)
Δ = 529
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{529}=23$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-7)-23}{2*12}=\frac{-16}{24}
=-2/3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+23}{2*12}=\frac{30}{24}
=1+1/4
