2x^2+150=42002x^2+150=4200.
We move all terms to the left:
2x^2+150-(42002x^2+150)=0
We get rid of parentheses
2x^2-42002x^2-150+150=0
We add all the numbers together, and all the variables
-42000x^2=0
a = -42000; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-42000)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
