 Simplify radicals w/ add/sub If there is a multi termed denominator-take the opposite and FOIL Polynomials separate into two change middle sign-factor individually-factor remaining Diff. of cube and square factor out first factor it will be neg. and divide-there will be one positive and one negative sum of cube and square factor out first it will positive and divide Simplify radicals Take out of radical by grouping sqrt out by 2, cubert out by 3, 4th root by 4, etc. Find x-intercept and y-intercept plug in zero-multiply out fractions-remember negatives slope intercept y=mx+b x-intercept (5,0)-x point and zero y y-intercept (0,5)-y point and zero x-and y-intercept=b slope y1-y2 ______ x1-x2 perpendicular line slope is negative reciprocal Polynomial real coeffecients opposite sign of the numbers and FOIL Negative leading coefficient -x^2-opens down -x^3-backwards n -x^4-m Positive leading coefficient x^2-opens up, x^3-n x^4-w perfect cubes 0, 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000 Long equation w/ fraction in exponents 2(5x^2+x+4) ------------------------ (6x+1)^2/3(2+x)^2(2-x)^2 V=1/3pir^2h for h V=-pir^2h ------- 3 3V= pir^2h -- ------ pir^2 pi^2 3v -- =h pir^2 A=P+Prt A=P+Prt - -- P P A=P(1+rt) A= P(1+rt) -- ------- 1+rt 1+rt A= P -- 1+rt Equation of a circle Must have mid-point (x - h)^2 + (y - k)^2 = r^2 Difference quotient (f(x+h)-f(x) ------------- h Max height above ground -find x value by pluggin into neg-b ---- 2a -plug into equation to find y value odd degree positive leading y goes to positive infinity as x goes to positive infinity degree is odd leading is neg y goes to negative infinity as x goes to positive infinity degree is even leading is positive y will go to positive infinity as x goes to positive infinity degree is even leading is negative y will go to negative infinity as x goes to positive infinity
