How do you solve using gaussian elimination or gauss-jordan elimination,

5 x + y + 5 z = 3

4 x - y + 5 z = 13

5 x + 2 y + 2 z = 2

https://socratic.org/questions/how-do-you-solve-using-gaussian-elimination-or-gauss-jordan-elimination-5x-y-5z-

x = 1 \frac{3 2}{9 9}

y = - 5 \frac{1 3 1}{1 9 8}

z = \frac{9}{2 2}

Explanation: To solve the system of linear equations

⎩ ⎪ ⎨ ⎪ ⎧ 5 x + y + 5 z = 3 4 x - y + 5 z = 13 5 x + 2 y + 2 z = 2

How do you factor completely

x y + 2 x + 4 y + 8

https://socratic.org/questions/how-do-you-factor-completely-xy-2x-4y-8

x y + 2 x + 4 y + 8 = (x + 4) (y + 2)

Explanation: Factor by grouping:

x y + 2 x + 4 y + 8

= (x y + 2 x) + (4 y + 8)

How do you find the roots, real and imaginary, of

y = (x + 1) (- 5 x + 5)

using the quadratic formula?

x = - 1

x = 1

Explanation: We do not Need the quadratic formula, since we get

(x + 1) (- 5 x + 5) = 0

x + 1 = 0

find all integer solutions for

x y + 1 = 3 (x + y)

https://math.stackexchange.com/questions/2119513/find-all-integer-solutions-for-xy1-3xy

We want to find a factorization if possible, so consider

x y - 3 x - 3 y + k = k - 1

as a re-writing of the condition. Then we can take any value for

k

to make a factorization possible, and

(x - 3) (y - 3) = x y - 3 k - 3 y + 9
