-x^2+4x+30=-10x^2-6+4x=
We move all terms to the left:
-x^2+4x+30-(-10x^2-6+4x)=0
We add all the numbers together, and all the variables
-1x^2-(-10x^2-6+4x)+4x+30=0
We get rid of parentheses
-1x^2+10x^2-4x+4x+6+30=0
We add all the numbers together, and all the variables
9x^2+36=0
a = 9; b = 0; c = +36;
Δ = b2-4ac
Δ = 02-4·9·36
Δ = -1296
Delta is less than zero, so there is no solution for the equation
