16x^2+24x=87

Solution for 16x^2+24x=87 equation:

16x^2+24x=87

We move all terms to the left:

16x^2+24x-(87)=0

a = 16; b = 24; c = -87;
Δ = b2-4ac
Δ = 242-4·16·(-87)
Δ = 6144
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:

$\sqrt{\Delta}=\sqrt{6144}=\sqrt{1024*6}=\sqrt{1024}*\sqrt{6}=32\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-32\sqrt{6}}{2*16}=\frac{-24-32\sqrt{6}}{32}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+32\sqrt{6}}{2*16}=\frac{-24+32\sqrt{6}}{32}
