Answer 1

@mathmate CAN you help?

Answer 2

@incomplte @Southern @Gabrielle0967 @Lemanual can you guys help?!?!

Answer 3

Hi, i think i can help you

Answer 4

the first question just wants you to recognise the highest power of the algebraic expression. Can you tell what the highest power is?

Answer 5

5 is the highest power.

Answer 6

Cool! You're right. So quantic is the 5th power, quartic is 4th, cubic is 3rd, and quadratic is 2. So quantic is the right option here

Answer 7

The second question just wants you to multiply out the expression

Answer 8

\[(-2x^2)(-5x^2+4x^3)= (-10x^4-8x^5). Rearranging \to put the highest powers first, we get (-8x^5-10x^4)\]

Answer 9

hope that helps.

Answer 10

would it be A also?

Answer 11

That would be B. I messed up my signs there. Should've been -8x^5+10x^4

Answer 12

so A and B can you help me with another one?
