Solution for 2(5+9/7)x=0 equation:

2(5+9/7)x=0


Domain of the equation: 7)x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

2(9/7+5)x=0

We multiply parentheses

18x^2+10x=0

a = 18; b = 10; c = 0;
Δ = b2-4ac
Δ = 102-4·18·0
Δ = 100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{100}=10$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(10)-10}{2*18}=\frac{-20}{36}
=-5/9
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+10}{2*18}=\frac{0}{36}
=0
