Answer 1

`\boxed{\boxed{\sf~x=7,-7}}`

Solution Steps:

______________________________

1.) Take the square root of both sides of the equation:

• 
  `√(x)=x`

• 
  `√(49)=7`

Answer 2

x = 7

x = -7

Step-by-step explanation:

x² = 49

• 
  `\bold{\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=√(f\left(a\right)),\:\:-√(f\left(a\right))}`

`\bold{x=√(49),\:x=-√(49)}`

√49 = 7

-√49 = -7

x = 7, x = -7
