X+3/4X=150
We move all terms to the left:
X+3/4X-(150)=0
Domain of the equation: 4X!=0We multiply all the terms by the denominator
X!=0/4
X!=0
X∈R
X*4X-150*4X+3=0
Wy multiply elements
4X^2-600X+3=0
a = 4; b = -600; c = +3;
Δ = b2-4ac
Δ = -6002-4·4·3
Δ = 359952
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}$$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{359952}=\sqrt{16*22497}=\sqrt{16}*\sqrt{22497}=4\sqrt{22497}$$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-600)-4\sqrt{22497}}{2*4}=\frac{600-4\sqrt{22497}}{8} $$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-600)+4\sqrt{22497}}{2*4}=\frac{600+4\sqrt{22497}}{8} $
