(a-b)^2-5(a-b)+7
You asked:
Evaluate the expression: \({\left( a - b \right)}^{2} - 5 \cdot \left(a - b\right) + 7\)
MathBot Answer:
Evaluated
\(\displaystyle {\left( a - b \right)}^{2} - 5 \cdot \left(a - b\right) + 7 = - 5 a + 5 b + \left(a - b\right)^{2} + 7 \)
Expanded
\[{\left( a - b \right)}^{2} - 5 \cdot \left(a - b\right) + 7 = a^{2} - 2 a b - 5 a + b^{2} + 5 b + 7\]
Factored
\[{\left( a - b \right)}^{2} - 5 \cdot \left(a - b\right) + 7 = a^{2} - 2 a b - 5 a + b^{2} + 5 b + 7\]
