(2 x3) times (5 x3)= 10 x6

Of course, it could also mean (2x)3 (5x)3 =(8x3 )(125x3 )=1000x6

It all depends on weather you mean the quantity 2x to the third or 2 multiplied by x to the third.

3 - 5x - 2x = 3 - 7x( 3 - 7x )2 = 9 - 42x + 49x2

5x-2x = 3

(2x + 3)(x + 1)

x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3

5x -2x = 3

2x2 + 5x + 3 Notice the first term, which can be rewritten as 2x times x. With this in mind, you can write the equation as...(2x + a)(x + b)...where -a and -b are the answers.You know that a times b is equal to 3.With a little trial and error, you will find:2x2 + 5x + 3 = (2x + 3)(x + 1)

2x-5x-3 -3x-3 -3(x+1)

-3(x-5)=2x -3x+15=2x 15=5x x=3

2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1

2x squared - 5x - 3 = (2x +1)(x -3)

5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3

lim x->.5 of (2x2 +5x-3)/(2x-1) First factor 2x2 +5x-3 as (2x-1)(x+3) Now note that the (2x-1) cancels out so you have lim x->0.5 of x+3 and this is 3.5
