I need help completing the square of a quadratic equation. ]
3x^2 + x - = 0
We need the coefficient of x^2 to be 1, divide equation by 3, then we have
x^2 + x - = 0
:
x^2 + x + ____ =
Find the value to complete the square; =
x^2 + x + = +
x^2 + x + = +
x^2 + x + =
Which is
=
Find the square root of both sides
x + = +/-
extract the perfect square
x + = +/-
Two solutions
x = +
and
x = -
we can write it
x =
and
x =
