Question

Solve using the quadratic formula:
x^2+7x=24

Answer 1

If you list the whole problem. I can help better

Answer 2

@Ms-Brains what do you mean by "listing the whole problem" ?

Answer 3

@shelby1290 I can help :D

Answer 4

Take a snip of it, and attach the link. :)

Answer 5

@AskMeLotss thank you!

Answer 6

your welcome

Answer 7

@Ms-Brains this IS the math problem. It's an application question. What more can I possibly say?

Answer 8

Step 1 :

Simplify x2 - 7x
Equation at the end of step 1 :

(x2 - 7x) - 24 = 0

Answer 9

The list of choices.. But never mind. cx You already git help. :3

Answer 10

what are the answer choices?
if you dont have any, i can still help also :)

Answer 11

It isn't a multiple choice question though.....

Answer 12

Step 2 :

Simplify x2-7x - 24
Trying to factor by splitting the middle term

Answer 13

Factoring x2-7x-24

The first term is, x2 its coefficient is 1 .
The middle term is, -7x its coefficient is -7 .
The last term, "the constant", is -24

Answer 14

Step-1 : Multiply the coefficient of the first term by the constant 1 • -24 = -24

Answer 15

It's an open response/application question. There aren't any choices.

Answer 16

Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -7

Answer 18

-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2
-3 + 8 = 5
-2 + 12 = 10
-1 + 24 = 23

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Answer 19

Equation at the end of step 2 :

x2 - 7x - 24 = 0
Step 3 :

Solve x2-7x-24 = 0

Answer 21

Solving x2-7x-24 = 0 by the Quadratic Formula .

According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :

- B ± √ B2-4AC
x = ————————
2A

In our case, A = 1
B = -7
C = -24

Accordingly, B2 - 4AC =
49 - (-96) =
145

Applying the quadratic formula :

7 ± √ 145
x = —————
2

√ 145 , rounded to 4 decimal digits, is 12.0416
So now we are looking at:
x = ( 7 ± 12.042 ) / 2

Two real solutions:

x =(7+√145)/2= 9.521

or:

x =(7-√145)/2=-2.521
