Answer, Solution, and Explanations:

Distribute the parentheses. (This means that you have to multiply each of the terms within the first parentheses by each of the terms within the second parentheses from left to right.)

=

Then, apply the minus - plus rules.

=

Simplify afterwards.

• For the :
• Multiply the numbers: 7 · 2 = 14, which results to:
• =
• Afterwards, apply the exponent rule.
• =
• Add 2 + 1 in the exponents part.
• =

• For :
• Just multiply these numbers: 7 · 5 = 35
• =

• For :
• Multiply one of these numbers: 9 · 2 = 18
• =
• Then, apply the exponent rule. ()
• =
• Lastly, add these numbers in the exponent part. (1 + 1 = 2)
• =

• For :
• Just multiply both of the numbers thereof.
• =

• For :
• Again, the same process just as stated a while ago.
• =

• For :
• Multiply.
• = 60

• Now, rearrange and rewrite them.
• =
• Add similar elements. ()
• =
• Add similar elements again. ()
• =

Therefore, your final answer is:

.

Answer:

14x³-17x²-69x+60

Step-by-step explanation:

Apply Distributive Property of Multiplication

(7x²+9x-12)(2x-5)

14x³+18x²-24x-35x²-45x+60

14x³-17x²-69x+60
