Answer:
x = -2 & -4
Step-by-step explanation:
√(x + 3) + 4 = 5
√(x + 3) = 5 - 4
√(x + 3) = 1
[√(x + 3)]² = (1)²
x² + 9 + 6x = 1
x² + 9 - 1 + 6x = 0
x² + 8 + 6x = 0
x² + 6x + 8 = 0
x² + (4x + 2x) + 8 = 0
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) = 0
(x + 4)(x + 2) = 0
x = -2 & -4
Hence,
Value of x is -2 & -4
Answer:
-2
Step-by-step explanation:
We start off by subtracting 4 on both sides giving us:
sqrt(x+3) = 5-4 = 1
So,
sqrt(x+3) = 1, and squaring both sides we get x+3 = 1
Therefore,
x = -2
