(-7(9x^2-18x+18)+(18x-18))=0

Solution for (-7(9x^2-18x+18)+(18x-18))=0 equation:

(-7(9x^2-18x+18)+(18x-18))=0


We calculate terms in parentheses: +(-7(9x^2-18x+18)+(18x-18)), so:

-7(9x^2-18x+18)+(18x-18)

We multiply parentheses

-63x^2+126x+(18x-18)-126

We get rid of parentheses

-63x^2+126x+18x-18-126

We add all the numbers together, and all the variables

-63x^2+144x-144

Back to the equation:

+(-63x^2+144x-144)


We get rid of parentheses

-63x^2+144x-144=0

a = -63; b = 144; c = -144;
Δ = b2-4ac
Δ = 1442-4·(-63)·(-144)
Δ = -15552
Delta is less than zero, so there is no solution for the equation
