Determine whether the monomials are like terms. IF they are, combine them. (If they are not like terms, enter NONE.) 2x^2, 8x^2 Determine whether the monomials are like terms. IF they are, combine them. (If they are not like terms, enter NONE.) 9x^2, 5x Determine whether the monomials are like terms. IF they are, combine them. (If they are not like terms, enter NONE.) -4y^4, -5y^4, 11y^4 Complete each step. (3x^2 + 2x - 6) + (2x^2 - 9x) = (3x^2 +) + (2x -) + (-6) = + (-7x) - 6 = 5x^2 - 7x - 6 Complete each step. (3x^2 + 6x - 2) - (6x^2 - 5x) = 3x^2 + 6x - 2 6x^2 5x = (- 6x^2) + (6x + 5x) - 2 =

Solution

2x^2 and 8x^2 are like terms cuz they both are x^2 terms...
Combinin em :
2x^2 + 8x^2 becomes
10x^2

--------------------------------------------------------------------

9x^2 and 5x

They aint like terms

Cant be combined

--------------------------------------------------------------------

-4y^4 , -5y^4 , 11y^4

They\'re all like cuz they all got y^4 in them.

Combinin\' em :
-4y^4 + (-5y^4) + 11y^4

-9y^4 + 11y^4

to get

2y^4

------------------------------------------------------------------

(3x^2 + 2x - 6) + (2x^2 - 9x)

3x^2 + 2x^2 + 2x - 9x + (-6)

5x^2 + (-7x) - 6

5x^2 - 7x - 6

-----------------------------------------------------------------

3x^2 + 6x - 2 - (6x^2 - 5x)

3x^2 + 6x - 2 - 6x^2 + 5x

(3x^2 - 6x^2) + (6x + 5x) - 2

-3x^2 + 11x - 2
