6\left(n\left(-2\right)^{2}-\left(-3\right)\right)=-25n
Multiply both sides of the equation by -5.
6\left(n\times 4-\left(-3\right)\right)=-25n
Calculate -2 to the power of 2 and get 4.
6\left(n\times 4+3\right)=-25n
The opposite of -3 is 3.
6n\times 4+18=-25n
Use the distributive property to multiply 6 by n\times 4+3.
24n+18=-25n
Multiply 6 and 4 to get 24.
24n+18+25n=0
Add 25n to both sides.
49n+18=0
Combine 24n and 25n to get 49n.
49n=-18
Subtract 18 from both sides. Anything subtracted from zero gives its negation.
n=\frac{-18}{49}
Divide both sides by 49.
n=-\frac{18}{49}
Fraction \frac{-18}{49} can be rewritten as -\frac{18}{49} by extracting the negative sign.
