2x^2+11x-6=0 How do you complete the square of this problem
:
The coefficient of x^2 should be 1, divide thru by 2
x^2 + x - 3 = 0
:
x^2 + x + __ = 3
:
(*)^2 = will complete the square, add to both sides
:
x^2 + x + = 3 +
:
x^2 + x + = +
:
x^2 + x + =
:
(x + )^2 =
:
Find the square root of both sides
x + = +/-
:
x + = +/-
Two solutions
x = +
x = =
and
x = -
x = = -6
:
:
You can confirm this by checking these values for x in the original problem
