Question

if graphing and factoring are applied to solve x^2+6x=-9, what could be the solution?

Answer 1

Another question, What could be the value of C that makes r^2-9r+C a perfect square?

Answer 2

?????????????

Answer 3

?=

Answer 4

what is the answer?

Answer 5

is that AC test?

Answer 6

\[(x+a)^2=x^2+xa+ax+a^2=x^2+2ax+a^2\]

Answer 7

so the answer is +3?

Answer 8

yes \(x=3\) is the solution to the first equation

Answer 9

thank you

Answer 10

What could be the value of C that makes r^2-9r+C a perfect square?

Answer 11

its a perfect square when\[r^2-9r+C=0\]\[r^2-2\times\frac92r+\sqrt C^2=0\]

Answer 12

The answer to the first question is x = -3.

Answer 13

your right @kropot72

Answer 14

Cool :)

Answer 15

we found \[(x+3)^2=0\]for this to be true \(x=-3\) (not +3)

Answer 16

please simplify the answer in the second question
i cannot understand

Answer 17

This is a partial graph of y = x^2 + 6x + 9 to give a graphical solution to the first question.
