Question

Write an equivalent expression without using grouping symbols.
-(9x³+8x+10)

Answer 1

Hi, Sharron. How are you? Can you understand what the question says?

Answer 2

It just tells you to express the polynomial in such a way that there are no parentheses.

Answer 3

Do you know how to distribute the minus sign amongst the terms inside?

Answer 4

i am not sure if the minus sign goes with all or just some of the numbers

Answer 5

would it be
-9x³+-8x+-10

Answer 6

Yeah, but take note that +- (you can think of this as +1 * -1) can simply be written as - (1*-1 = -1) . So that'd be -9x^3-8x-10.

Answer 7

thank you
