34-(2c+4)=2(c+5)c
We move all terms to the left:
34-(2c+4)-(2(c+5)c)=0
We get rid of parentheses
-2c-(2(c+5)c)-4+34=0
We calculate terms in parentheses: -(2(c+5)c), so:We add all the numbers together, and all the variables
2(c+5)c
We multiply parentheses
2c^2+10c
Back to the equation:
-(2c^2+10c)
-2c-(2c^2+10c)+30=0
We get rid of parentheses
-2c^2-2c-10c+30=0
We add all the numbers together, and all the variables
-2c^2-12c+30=0
a = -2; b = -12; c = +30;
Δ = b2-4ac
Δ = -122-4·(-2)·30
Δ = 384
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{384}=\sqrt{64*6}=\sqrt{64}*\sqrt{6}=8\sqrt{6}$$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-12)-8\sqrt{6}}{2*-2}=\frac{12-8\sqrt{6}}{-4} $$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-12)+8\sqrt{6}}{2*-2}=\frac{12+8\sqrt{6}}{-4} $
