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.

9a-4(2a+5). I really need help with this question

slava [35]

First you had to expanded form.

$-4(2a+5)=-8a-20$

$9a-8a-20$

Finally you can also add by similar to elements.

$9a-8a=a$

$a-20$

Final answer: $\boxed{=a-20}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
