Question

x^2-38x+326=0 please factor

Answer 1

\[x=19\pm \sqrt{35}\]

Answer 2

Just apply the quadratic formula

Answer 3

use the quadratic formula
\[x=\frac{-b \pm \sqrt {b^2-4ac}}{2a}, \]
which
A is the coefficient for the x^2 term
B is the coefficient for the x term
C is the coefficient for the x^0 term

Answer 4

Yup, robtotey has the correct answer and Kynosis gives the formula

Answer 5

Well it looks like I will need to start this from the beginning. This is new to me so I am lost. I have a word problem. It is about a ladder leaning against a bldg. distance from bottom of ladder to bldg is 18' less than the length of the ladder. How high up the side of the bldg is the top of the ladder if that distance is 1' less than the length of the ladder

Answer 6

Maybe I set it up wrong. I started with \[(x-18)^2+(x-1)^2=x^2\]

Answer 7

Is this right?

Answer 8

I agree with you Geminiman

Answer 9

finding the roots give you the factor of the equation indirectly. because equation are in the quadratic form is (x - n) ( x- n) with n being the root you have a factored equation. of \[( x - 19+√(35)) ( x - 19-√(35))\]

Answer 10

ok. then I did this formula: \[x^2-36+324+x^2-2x+2=x^2\]

Answer 11

I get x^2 - 38x + 325 = 0

Answer 12

ok I got x^2338x+326=0

Answer 13

Then you get (x - 25)(x - 13) = 0 which is
x = 25, 13

Answer 14

sorry typed it wrong. x^2-38x+326=0

Answer 15

When you took (x - 1)^2 Gem you had x^2 - 2x + 2 and it is actually x^2 - 2x + 1

Answer 16

ah ok that is why I got 326 instead of 325.

Answer 17

Thank you all for your help
