It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.

2x2 + 7x - 15 = (2x - 3)(x + 5)

(x + 1)(2x + 5)

7x2 -4x -5x2 +2x = 2x2 -2x

You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)

It is 9x

13x

(x + 5)(2x - 3)

Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.

2x+3 = 9x 3 = 9x-2x = 7x 7x = 3 x = 3/7

(x - 2)(2x - 3)

No

It is an equation and the value of x is 1

2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans

7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6

7x-4x+2x+5=2x+14 5x+5=2x+14 3x=9 x=3

-2x + 8 = 7x - 10 is technically an equation, in and of itself.

-2x squared

2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)

The value of x is 1

X = -3

(2x + 5)(7x - 3)

3.5

2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
