Question

Solve for x 7x^2+49=0

Answer 1

`7 {x}^(2) + 49 = 0 \\ 7( {x}^(2) + 7) = 0 \\ \frac{7( ({x}^(2) + 7) }{7} = (0)/(7) \\ {x}^(2) + 7 = 0 \\ {x}^(2) = - 7`

NOTE THERE IS NO SOLUTION FOR THE GIVEN EQUATION SINCE THE SQUARE OF ANY NUMBER CANNOT GIVE A NEGATIVE NUMBER.

THE SQUARE OF ANY NUMBER WHETHER IT'S POSITIVE OR NEGATIVE ALWAYS GIVES A POSITIVE NUMBER.

GOODLUCK!!
