Answer:
4x²+ 6x - 4 =0
2xb = 6x
2b =. 6
b = 6/2
b² = (6/2)²
4x² + 6x - 4 =0 divide by 4
16 x² + 24 x - 16 =0
16 x²+24 x = 16
Add (6/2)²on both sides
16 x² + 24 x + (6/2)² = 16 + (6/2)²
(4x²) + 2 (2x)(6/2) + (6/2)² = 16 + 36 /4
It is in the form of (a+b)²
(4x + 6/2)² = 64 + 36/4
(4x + 6/2)² = 100 /4
(4x + 6/2 )² = 25
(4x + 6/2). = ±√25
4x + 3 = ±5.
4x = +5- 3 4x = -5 -3
4x = 2 4x = -8
x= 2/4. x= -8/4
x= 1/2. x= -2
I hope it will help you mate!
