x2= 14

X = 14/2

X= 7 our answer kindly make it brainlieast

Answer 2

Step-by-step explanation:

cross multiplying we get

${x}^{2} - 15 = - 1( {x }^{2} - 17)$

${x}^{2} - 15 = - {x}^{2} + 17$

${x}^{2} + {x}^{2} = 17 + 15$

$2 {x}^{2} = 32$

${x}^{2} = 16$

$x = \sqrt{16}$

$x = 4$

$or$

$x = - 4$
