The solution to the equation 2x plus 2 is 2(x + 1).

2x + 4 = 2 2x = -2 x = -1

(2x + 1)(x + 2)

2 plus 1-x divided by.

If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)

x plus 2 = x + 2 x plus x = 2x

3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3

Integral of 1 is x Integral of tan(2x) = Integral of [sin(2x)/cos(2x)] =-ln (cos(2x)) /2 Integral of tan^2 (2x) = Integral of sec^2(2x)-1 = tan(2x)/2 - x Combining all, Integral of 1 plus tan(2x) plus tan squared 2x is x-ln(cos(2x))/2 +tan(2x)/2 - x + C = -ln (cos(2x))/2 + tan(2x)/2 + C

4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3

4x + 2 = 2x + 5 Subtract through by 2x 2x + 2 = 5 Subtract through by 2 2x = 3 Divide through by 2 x = 1.5 ■

2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)

-2x+2

2x - 6.

x = 7

2x+2=x+5 x=3

Simplify 4x + 3 = 2x + 8 2x = 5 x =2½

(2x + 1)(2x + 1) or (2x + 1)2

(2x + 3)(x + 1 ) = 2x^2 +5x +3

8x-7 plus 2x equals 6 plus 5x plus 2?

4x + 1 = 2x + 5 4x + 1 - 2x = 2x + 5 - 2x 2x + 1 = 5 2x + 1 - 1 = 5 - 1 2x = 4 2x/2 = 4/2 x = 2

It can be. x^2 + x + 1 is a factor of 2x^2 + 2x + 2

There is no solution to: 4(2x + 2) + 12 > 1004(2x + 2) + 12 > 100 For 4(2x + 2) + 12 > 1004(2x + 2) + 12 to have a solution x < -1 which makes 1004(2x + 2) + 12 < 12, BUT 1004(2x + 2) + 12 is supposed to be greater than 100. Perhaps there is a missing operator in the digits of 1004?

The additive inverse is x5 + 2x - 2.
