10x+6x(4x-10)+x^2=


10x+24x^2-60x+x = -50x+25x^2

or ; 25x^2-50x

100

Distribute -8(3x - 10)

24x + 80  (they MUST have + 80, not - 80)

31x+4x(5x+10)=

31x+20x^2+40x = 71x+20x^2

or; 20x^2+71x

54as^3z+89s^3az

Like terms - both letters are the same, order does not matter.

400

Distribute & Combine:

-8x + 7y - 8y - 10(3x + 3y) = 

-8x+7y-8y-30x-30y = -8x - 30x = -38x and

 7y-8y-30y=-31y so 

-38x-31y; OR; -31y-38x

400

10r-4r(5r-2)+r^2

=10r-20r^2+8r+r^2= -19r^2+18r

or; 18r-19r^2

400

Distribute and combine like terms

7 + 3(7y - 5) - 20y + 8= 

7 + 21y - 15 - 20y + 8

7 - 15 + 8 = 0 so they cancel

21y - 20y = y or 1y
