It is possible to use the distributive property to simplify the expression
2(ab−7)(3+a)
To solve this problem, we'll follow these steps:
- Step 1: Distribute the expressions inside the parentheses.
- Step 2: Multiply and simplify expressions inside first, then outside.
Let's work through each step:
Step 1: Consider the expression (ab−7)(3+a). Apply the distributive property:
- First, distribute ab to both terms inside the second parentheses:
ab⋅3=3ab
ab⋅a=a2b
- Next, distribute −7 to both terms inside the second parentheses:
−7⋅3=−21
−7⋅a=−7a
Combining these, we have:
(ab−7)(3+a)=3ab+a2b−21−7a.
Step 2: Multiply through by the factor 2 outside the parentheses:
2⋅3ab=6ab
2⋅a2b=2a2b
2⋅−21=−42
2⋅−7a=−14a
Thus, our expression becomes:
6ab+2a2b−42−14a.
Therefore, the solution to the problem is 6ab+2a2b−42−14a.
Yes, 6ab+2a2b−42−14a
