900=4.929x^2-23.171x+38.100
We move all terms to the left:
900-(4.929x^2-23.171x+38.100)=0
We get rid of parentheses
-4.929x^2+23.171x-38.100+900=0
We add all the numbers together, and all the variables
-4.929x^2+23.171x+861.9=0
a = -4.929; b = 23.171; c = +861.9;
Δ = b2-4ac
Δ = 23.1712-4·(-4.929)·861.9
Δ = 17530.115641
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{-(23.171)-\sqrt{17530.115641}}{2*-4.929}=\frac{-23.171-\sqrt{17530.115641}}{-9.858} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(23.171)+\sqrt{17530.115641}}{2*-4.929}=\frac{-23.171+\sqrt{17530.115641}}{-9.858} $
