Answer:
x = 4 and 2
Step-by-step explanation:
hope it's helpful
√10x – 4 = x + 2
Squaring both sides we get,
(√10x – 4)² = (x + 2)²
After squaring
10x – 4 = x² + 4x + 4
x² + 4x – 10x + 4 + 4
x² – 6x + 8 = 0
After solving the quadratic equation we get the value of x;
(x₁ , x₂) = (4, 2)
Thus, The value of x is 4 and 2

<u>For </u><u>Verification</u>;</h3>
For x₁
√10x – 4 = x + 2
Plug in 4 for x
√10(4) – 4 = 4 + 2
√36 = 6
x = 4
Here, L.H.S = R.H.S
For x₂
√10x – 4 = x + 2
plug in 2 for x
√10(2) – 4 = 2 + 2
√16 = 4
x = 2
Here, L.H.S = R.H.S
