h(x)=x^2+10x+32

snowflake0531:

What do you need to do?

snowflake0531:

Do you need to factor it or...

KynxKatz:

One sec

KIllerwolfdaone:

|dw:1615933010541:dw| i dont know if this could help but i tried my best

KynxKatz:

Let's solve for h. hx=x^2+10x+32 Step 1: Divide both sides by x Hx/x=X^2+10x+3x/x H= X^2+10x+3x/x

snowflake0531:

That's not how it works

snowflake0531:

You

KIllerwolfdaone:

i tried to do a graph but it turned out wrong

snowflake0531:

We're doing h of x Where did you get that from

snowflake0531:

Most of the time, given an equation, you're trying to find the roots, the zeroes of them

snowflake0531:

In h(x)=x^2+10x+32 x^2 + 10x +32 We can already see that it's not possible to do a perfect factoring thing So, we pull out the Quadratic Formula

snowflake0531:

Since we know that a=1 b=10 c=32 We can put it in [-10 +- sqrt(100-128)]/2

snowflake0531:

So, to simplify, it is [-10 +- sqrt(-28)]/2

snowflake0531:

To simplify again [-10 +- 2sqrt-7]/2

snowflake0531:

To again simplify It would be -5 +- sqrt(-7)

snowflake0531:

We can take out the -1 part by putting it as i So it owuld be -5 +- isqrt7

snowflake0531:

i, as in the imaginary number

snowflake0531:

You don't want that decimal point, that's not exact

KynxKatz:

I do

KynxKatz:

Read the picture before u suggest anything pls

snowflake0531:

But you're not the one that's doing htis

KynxKatz:

𝑥=−5−2.64575

snowflake0531:

We need to factor So It becomes (x+5 -isqrt7)(x+isqrt7)

KynxKatz:

Imma just leave this to you

snowflake0531:

I'm done

KynxKatz:

Oh mk great
