7s(-3s+1)=4(3+s)

Solution for 7s(-3s+1)=4(3+s) equation:

7s(-3s+1)=4(3+s)

We move all terms to the left:

7s(-3s+1)-(4(3+s))=0

We add all the numbers together, and all the variables

7s(-3s+1)-(4(s+3))=0

We multiply parentheses

-21s^2+7s-(4(s+3))=0


We calculate terms in parentheses: -(4(s+3)), so:

4(s+3)

We multiply parentheses

4s+12

Back to the equation:

-(4s+12)


We get rid of parentheses

-21s^2+7s-4s-12=0

We add all the numbers together, and all the variables

-21s^2+3s-12=0

a = -21; b = 3; c = -12;
Δ = b2-4ac
Δ = 32-4·(-21)·(-12)
Δ = -999
Delta is less than zero, so there is no solution for the equation
