Ch. 2
Simplify
Distribute (×) then Combine (+ or - ) like terms
IE) −3𝑥 − (2𝑥 − 4) + 6𝑥 − 9 + 𝑥 2
Ch. 3
Solve
Get variable by itself by
+/-
and
×/÷
IE) −2𝑥 + 4 = −6 + 𝑥

Inequalities
If you divide by NEGATIVE-FLIP
If you don’t divide by a
negative-don’t flip it
< > open
≤ ≥ closed
or STAT IT
(−3,2) and
(−1, −2)
IE) 2𝑥 + 6 < −4
IE)4𝑥 − 𝑦 < −2

(2 equations)
2𝑥 − 3𝑦 = −3
Ch.8
Simplify
Exponents
Add/Subtract -MUST BE LIKE- Exponent: stay same
IE) 𝑥 − 𝑥
IE) 𝑥 + 𝑥 2 − 3𝑥
Multiply- add exponents
IE)−2𝑥 (−3𝑦)(−3𝑥)(2𝑦6 )
Divide -subtract exponents
IE)

25𝑎5 𝑏5 𝑐 2 𝑑 10
Product to a Power Write it out
IE) (2𝑥𝑦 5 )3

Simplify
*get rid of (parenthesis): Distribute then Combine like terms
IE) (3𝑚 + 4) − (2𝑚2 − 6𝑚 + 5)
IE)−5𝑎2 (4𝑎3 − 1)
IE) (4𝑎 + 5)(7𝑎 − 6)2
Ch.10
Quadratics
Quadratics –Standard Form: 𝑎𝑥 2 + 𝑏𝑥 + 𝑐 = 0
𝑎𝑥 2 + 𝑏𝑥 + 𝑐 = 𝑦
The easiest way to solve a Quadratic is the X-intercepts-check with TABLE (must have 0)
To Graph
X=
𝑦 = 𝑥 2 + 2𝑥 − 3
Last Minute Reminders---LOOK AT THIS RIGHT BEFORE THE TEST TO REVIEW
Parallel lines - same slope
quadratic-x-int, roots, zeroes, solutions ALL SAME
THING
Parent Functions-parents are positive!!
Linear: 𝑦 = 𝑥 (line)
Domain:
Range:
x-independent
y- dependent
Quadratic: 𝑦 = 𝑥 2 (parabola)
Functions: X can’t repeat or vertical line test
Function Notation: f(x) = y
Direct Variation: line that goes thru 0
Constant of Variation: the slope
Percent’s-change to a decimal and multiply
Systems-find the intersection
If you don’t know how to do a
problem try to

Proportion (if you have a

comparison)
y= and look in the table
x-intercept after it equals 0
 INTERSECTION –system
 STAT
 FORMULA CHART- don’t

forget you have one!!

Graph it—don’t forget you have
graph paper
PLUG IN – the answer choices
 D=rt (dirt)
 Don’t use a table for
inequalities(look at the
shade)


Sequence of #’s –y=

Divide by a negative-flip it
< is less than----shade to the left
or down
> is greater than---shade to the
right or up
< > open
≤ ≥ closed
Multiply-add exponents
Divide-subtract exponents
(−𝟑)𝟐 𝒊𝒔 𝒈𝒐𝒐𝒅 −𝟑𝟐 not good
Less than---flip the order
Slope ----rate, per, what it is
changing by
Y-intercept—the fixed, initial, flat
fee, starts
Vertical lines are X=
Less slope-less steep
More slope- more steep
Is at least ≥
Is at most ≤
Less than- flip around word
