Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
Answer:
2x - 3
Step-by-step explanation:
The Distributive Property of Multiplication applies here. Multiply each of the two terms inside parentheses by-1/4: 2x - 3
You can take out 2x^3 from both terms making it
2x^3 (15+8x^2)
Answer is B
