Answer:
√5/2
Step-by-step explanation:
Step 1: divide everything by 2
x² + 4x - 1 = 0
Step 2: transpose 1 and leave blank
x² + 4x + __ = 1 + __
Step 3: add the number that will make it a perfect square trinomial on both sides
x² + 4x + 4 = 1 + 4
Step 4:
√(x + 2)² = √5
Step 5: find square root on both sides
x + 2 = √5
Step 6: Divide both sides by 2
x = √5/2
kita ko lang po bio nyo anong gc po yan omg
