ELEN [110]

30-f+8f=30

30+7f=30

30-30+7f=30-30

7f=0

Divde by 7

7f/7=0/7

Cross out 7 and 7, divide by 7. Becomes 1*1*f=f

[ Step One ] Remove Parenthesis: (a) = a

$\bold{x^2-9x+2+4x^2-5x+1-\left(5x^2-5\right)}$

[ Step Two ] Simplify $\bold{-\left(5x^2-5\right)}$

$\bold{-5x^2+5}$

[ Step Three ] Rewrite Equation

$\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}$

[ Step Four ] Simplify $\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}$
