1/4x-10x=15
We move all terms to the left:
1/4x-10x-(15)=0
Domain of the equation: 4x!=0We add all the numbers together, and all the variables
x!=0/4
x!=0
x∈R
-10x+1/4x-15=0
We multiply all the terms by the denominator
-10x*4x-15*4x+1=0
Wy multiply elements
-40x^2-60x+1=0
a = -40; b = -60; c = +1;
Δ = b2-4ac
Δ = -602-4·(-40)·1
Δ = 3760
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{3760}=\sqrt{16*235}=\sqrt{16}*\sqrt{235}=4\sqrt{235}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-60)-4\sqrt{235}}{2*-40}=\frac{60-4\sqrt{235}}{-80} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-60)+4\sqrt{235}}{2*-40}=\frac{60+4\sqrt{235}}{-80} $
