(=25x^2+30x+36)
We move all terms to the left:
(-(25x^2+30x+36))=0
We calculate terms in parentheses: +(-(25x^2+30x+36)), so:We get rid of parentheses
-(25x^2+30x+36)
We get rid of parentheses
-25x^2-30x-36
Back to the equation:
+(-25x^2-30x-36)
-25x^2-30x-36=0
a = -25; b = -30; c = -36;
Δ = b2-4ac
Δ = -302-4·(-25)·(-36)
Δ = -2700
Delta is less than zero, so there is no solution for the equation
