factorise (a+b)^2+9(a+b)+18
You asked:
Factor the expression: \(\displaystyle {\left( a + b \right)}^{2} + 9 \cdot \left(a + b\right) + 18\)
MathBot Answer:
The polynomial factors into the product: \[{\left( a + b \right)}^{2} + 9 \cdot \left(a + b\right) + 18 = \left(a + b + 3\right) \left(a + b + 6\right)\]
