0.3x(4x-15)+0.5x=62
We move all terms to the left:
0.3x(4x-15)+0.5x-(62)=0
We add all the numbers together, and all the variables
0.5x+0.3x(4x-15)-62=0
We multiply parentheses
0x^2+0.5x+0x-62=0
We add all the numbers together, and all the variables
x^2+1.5x-62=0
a = 1; b = 1.5; c = -62;
Δ = b2-4ac
Δ = 1.52-4·1·(-62)
Δ = 250.25
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1.5)-\sqrt{250.25}}{2*1}=\frac{-1.5-\sqrt{250.25}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1.5)+\sqrt{250.25}}{2*1}=\frac{-1.5+\sqrt{250.25}}{2} $
