Question

write -2x^2(-5x^2+4x^3) in standard form ?? explain?? :)

Answer 1

First you need to distribute/simplify, then worry about the standard form

Answer 2

i haven't done this in awhile but i know i distribute the -2x^2 to the paranthesis but do i add -2 to -5 so that becomes -7x^4 but idk

Answer 3

so lost :S

Answer 4

You're distributing - this means you need to multiply everything

a(b+c) = ab + ac

eg

2x(4x+3) = \[\Large 2x(4x+3) = 2*4*x*x + 2*3*x = 8x^2 + 6x\]

Answer 5

thats not any of the answers to the question D:

Answer 6

Answer 7

OH omfg i feel so dumb

Answer 8

Answer 9

Answer 10

Answer 11

^correct, the negative

Answer 12

Now standard form just means you need to change the order, put the highest power of x first.
