Sure! Here’s how a 7th grader might rewrite the expression \((3x - 5)(2x + 2)\) using the Distributive Property:
To simplify \((3x - 5)(2x + 2)\), we can use the Distributive Property where we multiply each term in the first part by each term in the second part. Here’s how we do it step by step:
-
First, we take \(3x\) and multiply it by both terms in the second parentheses:
- First, \(3x \cdot 2x = 6x^2\) (this is like multiplying the numbers and adding the exponents)
- Then, \(3x \cdot 2 = 6x\) (just multiply the numbers)
-
Next, we take \(-5\) and multiply it by both terms in the second parentheses:
- First, \(-5 \cdot 2x = -10x\) (negative five times positive two gives negative ten)
- Then, \(-5 \cdot 2 = -10\) (negative five times positive two gives negative ten again)
-
Now, we combine everything we got together: \[ 6x^2 + 6x - 10x - 10 \]
-
Finally, we need to combine like terms (the \(6x\) and \(-10x\)):
- So, \(6x - 10x = -4x\)
Putting it all together, we get: \[ 6x^2 - 4x - 10 \]
So, the simplified version of \((3x - 5)(2x + 2)\) is: \[ 6x^2 - 4x - 10 \]
And that’s how you use the Distributive Property to simplify that expression!
