Anastaziya [24]

The equation has -25, so the factored answer needs to be able to multiply and have a negative answer.

The missing part would be (x-5)

4 raised to power two minus 8u minus 9=0​
coldgirl [10]

Answer:

x can be 3, -3, i, or -i.

Step-by-step explanation:

If you can't find the factoring by looking at this, simplify the equation.

let  

x

2

=

y

to make things easier to see

Now we have  

y

2

−

8

y

−

9

=

0

See it now?

We can factor into  

(

y

−

9

)

(

y

+

1

)

Now substitute back in  

x

2

for  

y

.

(

x

2

−

9

)

(

x

2

+

1

)

Since  

(

x

2

−

9

)

is a difference of two squares,

(

x

−

3

)

(

x

+

3

)

Now we have  

(

x

−

3

)

(

x

+

3

)

(

x

2

+

1

)

x can be 3, -3 for the first two parts

x

2

+

1

=

0

can become  

x

2

=

−

1

Taking the positive and negative root means  

x

=

±

√

−

1

Thus  

x

=

±

i

in addition to 3 and -3.

Find the m please it’s due today . (-11,5) & (2,-4)
d1i1m1o1n [39]

Answer:

m = \frac{-9}{13}

Step-by-step explanation:

I'm assuming by m, you mean the slope.

You have two points. (-11, 5) and (2, -4)

  • m = change in y-value ÷ change in x-value

1) Substitute in the points.

m = \frac{(-4)- 5}{2 - (-11)}

2) Solve.

  • -4 - 5 = -9
  • 2 - (-11) = 13

So, the slope would equal \frac{-9}{13}.
