Pls n thx
1 answer:
Answer:
x = - 2 ± 
Step-by-step explanation:
To solve the equation using the method of completing the square.
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
add ( half the coefficient of the x- term )² to both sides
x² + 2(2) x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ±
( subtract 2 from both sides )
x = - 2 ±
← exact solution

Factor out a 3x:
3x(x2+4x+6)
Since you can't factor out the quadratic that's as far as it goes:
