Answer: A) (x + 3)^2 + 6

Step-by-step explanation:

x^2 + 6x + 15

Subtract 15 from both sides of the equation.

x^2 + 6x = -15

Complete the equation and add to both sides. Since (6 = 3 + 3), (3 x 3 = 9)

x^2 + 6x + 9 = -15 + 9

Simplify

(x + 3)^2 = -6

Add 6 to both sides of the equation

(x + 3)^2 + 6

One solution to a quadratic function, h, is given.

Margaret [11]

Answer:

B. The other solution to function $h$ is $-4-i\,7$ .

Step-by-step explanation:

From Algebra, we remember that quadratic functions of the form $a\cdot x^{2}+b\cdot x + c$ has solutions of the form:

$x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}$ , where both are complex if and only if $\sqrt{b^{2}-4\cdot a \cdot c}< 0$ .

Hence, if one solution of the quadratic function is $-4+i\,7$ , then the other solution is $-4-i\,7$ . The correct answer is B.
