25 POINTS AND BRAINEIST ANSWER IF YOU ARE SURE. Also, have a great day What number would you add to both sides of x2 + 7x = 4 to complete the square? 22 72 StartFraction 7 squared Over 2 EndFraction (StartFraction 7 Over 2 EndFraction) squared

12.25

Explanation

x² + 7x = 4

The number that should be added on both sides is the square of half the coefficient of x.

That is (7/2)².

(7/2)² = 7²/2²

        = 49/4

         = 12.25

∴ x² + 7x + 3.5² = 4 + 12.25

(x +  3.5) ² = 16.25
