You asked:
Evaluate the expression: \(-{\left( 2 b - 3 a \right)}^{2} - 18 {b}^{2} + 12 a b - 10 {a}^{2}\)
MathBot Answer:
Evaluated
\(\displaystyle -{\left( 2 b - 3 a \right)}^{2} - 18 {b}^{2} + 12 a b - 10 {a}^{2} = - 10 a^{2} + 12 a b - 18 b^{2} - \left(- 3 a + 2 b\right)^{2} \)
Expanded
\[-{\left( 2 b - 3 a \right)}^{2} - 18 {b}^{2} + 12 a b - 10 {a}^{2} = - 19 a^{2} + 24 a b - 22 b^{2}\]
Factored
\[-{\left( 2 b - 3 a \right)}^{2} - 18 {b}^{2} + 12 a b - 10 {a}^{2} = - 19 a^{2} + 24 a b - 22 b^{2}\]
