how to do these

[bitter coral]

What did you tried on the first photo

And i don't understand the second btw

[main cradle]

Neither do I, I feel like the rest got cut off

[bitter coral]

yeah

[main cradle]

The first one you are given one of the factors, (x-k). You can divide the equation by that factor (because its on both sides), and then solve for x

To get the other factor

[river condor]

I resend the second one

What step are you on?
1. I don't know where to begin.
2. I have begun but got stuck midway.
3. I got an answer but I was told that it's wrong.
4. I got an answer and would like my work checked.
5. I have a question about someone else's work/solution.
6. I have completed the problem and don't need help anymore. Thank you.
7. None of the above

This might be answer for first

[ocean copper]

do you know how to find the roots of a quadratic equation?

!noanswers

The purpose of this server is to help you learn, not to hand out answers. Do not ask someone to give you the answer directly.

[river condor]

yea but this question is too hard

[ocean copper]

start by finding the roots of the quadratic equation then

[river condor]

I know a+B = 7

aB = p

[main cradle]

How?

[river condor]

sum of roots = -b/a and product of roots = c/a

right

[ocean copper]

that's unlikely to be helpful here because we don't know what p is. so finding "two numbers that add up to b and multiply to ac" is going to be more work than using the quadratic formula

[river condor]

for this question

[river condor]

what's the first step

[ocean copper]

using the quadratic formula

[river condor]

ok

[wheat lodge]

I think you have to find the value of p like this

[river condor]

I got 49±√49-4p /2

then what's the next step

[wheat lodge]

just find the value of p for c and d now just like I did if you are asking me

[river condor]

ok

[river condor]

how do I do this
