Subtract L from both sides.
the expression now becomes,
S−L=−rL
2)Divide by L on both sides.
S−LL=−r
3)Multiply with a negative sign on both sides in the final step to obtain the expression in terms of r so the answer is #(L-S)/L = r#

Find the difference (5a^2+4ab-3b^2)-(-5ab+4b^2+3a^2)

Vesna [10]

Answer:

$\boxed{\bold{2a^2+9ab-7b^2}}$

Step By Step Explanation:

Remove Parenthesis: (a) = a

$\bold{5a^2+4ab-3b^2-\left(-5ab+4b^2+3a^2\right)}$

Simplify $\bold{-\left(-5ab+4b^2+3a^2\right)}$

$\bold{5ab-4b^2-3a^2}$

Rewrite Equation:

$\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

Simplify $\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

$\bold{2a^2+9ab-7b^2}$
