Find the values of x in this equation: x – 15 x = 2 . a. -7, 3 b. -5, 2 c. -7, 5 d. -2, 5 e. -3, 5

Step-by-step explanation:

The given expression is x- = 2

and we have to solve this for the value of x,

( x- ) = (2)

x² - 15 = 2x

x² - 2x - 15 = 0

x² - 5x + 3x - 15 = 0

x ( x-5 ) + 3(x - 5) = 0

( x+3 )( x-5 ) = 0

( x+3) = 0

x = -3

or ( x- 5 ) = 0

x = 5

Therefore, x = -3 and 5 will be the solution.
