-12(x-12)=-9(1+7x)x=

Solution for -12(x-12)=-9(1+7x)x= equation:

-12(x-12)=-9(1+7x)x=

We move all terms to the left:

-12(x-12)-(-9(1+7x)x)=0

We add all the numbers together, and all the variables

-12(x-12)-(-9(7x+1)x)=0

We multiply parentheses

-12x-(-9(7x+1)x)+144=0


We calculate terms in parentheses: -(-9(7x+1)x), so:

-9(7x+1)x

We multiply parentheses

-63x^2-9x

Back to the equation:

-(-63x^2-9x)


We get rid of parentheses

63x^2+9x-12x+144=0

We add all the numbers together, and all the variables

63x^2-3x+144=0

a = 63; b = -3; c = +144;
Δ = b2-4ac
Δ = -32-4·63·144
Δ = -36279
Delta is less than zero, so there is no solution for the equation
