X^2+19x+16X=0

Solution for X^2+19x+16X=0 equation:

X^2+19X+16X=0

We add all the numbers together, and all the variables

X^2+35X=0

a = 1; b = 35; c = 0;
Δ = b2-4ac
Δ = 352-4·1·0
Δ = 1225
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1225}=35$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(35)-35}{2*1}=\frac{-70}{2}
=-35
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(35)+35}{2*1}=\frac{0}{2}
=0
