(9z+8)2 (9z+8)(9z+8)  An item raised to the second power is that item multiplied times itself (9z+8)9z + (9z+8)8  Using the distributive property 9z(9z+8) + 8(9z+8)  Simply rewriting 9z*9z + 9z*8 + 8*9z + 8*8  Using...

There are a few ways to do this. (14x-28y)/[-7(x-2y)] [14(x-2y)/[-7(x-2y)]  Factor 14 out of each term of the numerator 14/-7                      Cancel (x-2y) out of the numerator...

12-7*6+19-14=11 (answer)

Add the parentheses based on highest order of operation, then left to right. example: 4-3*7-12/6+2 = x 4-(3*7)-(12/6)+2 = x  Multiplication and division are higher order than add and subtract, but                                     ...

x(x-8) + (x-8) Looking at you can see that (x-8) is in both terms if you replaced (x-8) with y you'd have x(x-8) + (x-8) xy + y = xy + 1y  where y = x-8 y(x+1) factor the y out (x-8)(x+1) simply replace y with it's original value of x-8. You can...

Remember that when multiplying (AX + B)(CX +D) you get (AC)X^2 + (AD + CB)X + BD So I look for the factors of the first and third terms then try to combine them to get the coefficient of the second term. (Hint: Prime Factors are very useful here) Factors of +1...
