Answer:
x = ±
Step-by-step explanation:
Given
3x² + 2 x - 5 = 0 ( add 5 to both sides )
3x² + 2 x = 5
Before completing the square we require the coefficient of the x² term to be 1
Factor out 3 from each term on the left side
3(x² + x ) = 5
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + x
3(x² + 2( )x +
-
) = 5
3(x + )² + ( 3 × -
) = 5
3(x + )² -
= 5 ( add
to both sides )
3(x + )² =
( divide both sides by 3 )
(x + )² =
( take the square root of both sides )
x + = ±
= ±
( subtract
from both sides )
x = - ±
Thus
x = - -
= -
x = - +
=
