Question

What number should be added to both sides of the equation to complete the square x^2 + 3x = 6​

Answer 1

Answer:

+ $\frac{9}{4}$

Step-by-step explanation:

To complete the square, with the coefficient of the x² term = 1

add ( half the coefficient of the x- term)² to both sides

x² + 3x + ($\frac{3}{2}$)² = 6 + ($\frac{3}{2}$)²

x² + 3x + $\frac{9}{4}$ = 6 + $\frac{9}{4}$
