Question

If x + 1x = 4, then the value of x² + 1x2​

Answer 1

Step-by-step explanation:

$x + 1x = 4 \: \: or \: \: x + x = 4 \\ 2x = 4 \: \: or \: \: x = \frac{4}{2} = 2 \\ \\ {x}^{2} + 1 {x}^{2} = 2 {x}^{2} \\ = 2 \times {2}^{2} = 8$

Answer 2

Step-by-step explanation:

x +1x = 4

2x = 4

x = 2
