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.

Option E is the answer.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
