9x^2=-73+-70
We move all terms to the left:
9x^2-(-73+-70)=0
We add all the numbers together, and all the variables
9x^2-(-143)=0
We add all the numbers together, and all the variables
9x^2+143=0
a = 9; b = 0; c = +143;
Δ = b2-4ac
Δ = 02-4·9·143
Δ = -5148
Delta is less than zero, so there is no solution for the equation
