Question

Solving Quadratic Equations by Factoring

I'm stumped on this one... could somebody explain it to me???

n^2 - 10n + 22 =-2

Answer 1

have you done quadratic factoring yet?

Answer 2

Yes. I am just stuck on the part of I know you have to use 2 numbers that times to get the 10n but what do i do with the 22?

Answer 3

\(\large n^2 - 10n + 22 =-2\implies
\begin{array}{cccllll}
n^2 &- 10n &+ 24 =0\\
&\uparrow &\uparrow\quad \\
&-6-4&-6\cdot -4
\end{array} \)

Answer 4

Omg... I feel really blonde now because I already knew that... Sorry to bother you.!

Answer 5

Can I ask one more thing??? How would you set it up though. Like n(-6-4) and(or) n(-6x-4)???

Answer 6

\(\large
\begin{array}{cccllll}
n^2 &- 10n &+ 24 =0\\
&\uparrow &\uparrow\quad \\
&-6-4&-6\cdot -4
\end{array} \implies (x-6)(x-4)=0\)

Answer 7

ahemm is "n" =) so \(\large
\begin{array}{cccllll}
n^2 &- 10n &+ 24 =0\\
&\uparrow &\uparrow\quad \\
&-6-4&-6\cdot -4
\end{array} \implies (n-6)(n-4)=0\)

Answer 8

Okayy Thankyou!!!
