The square of the number is 3 more than half the number,find the possible values of the number

1 answer

x = your number

The square of the number is 3 more than half the number mean:

x² = x / 2 + 3

Subtract x / 2 + 3 to both sides

x² - ( x / 2 + 3 ) = x / 2 + 3 - ( x / 2 + 3 )

x² - x / 2 - 3 = 0

Try to solve this equation.

The solutions are:

x = - 3 / 2 and x = 2
