User: Factor 49t 6 - 4k 8

Weegy: 49t^6 - 4k^8 = (7t^3 + 2k^4)(7t^3 - 2k^4)

User: Factor -5x 2 y + 10xy - 15xy 2

Weegy: Factor completely: -5x^2y + 10xy - 15xy^2 is -5xy(x - 2 + 3y).

User: Factor completely x^2 - 10x + 24

Weegy: 2(x-7) = 10x +18 2x - 7 = 10x +18 -7+ 18 = 10x -2x 11 = 8x x=11/8

User: Solve the following system of equations. 2x + y = 3 x = 2y - 1

Weegy: 2x + 3y=40- >(1); -2x + 2y=20- >(2); Adding (1) and (2), we get: 5y = 60; y = 12, x = 2.

User: Solve the following system of equations. 3x + 2y - 5 = 0 x = y + 10

User: solve 2x + y = 3

Weegy: 2x = 20

x = 20/2

x = 10

User: solve x = 2y - 1

Weegy: .) 2x + y = 3 2.) x - 2y = -1 If equation 1 is multiplied by 2 and then the equations are added, the result is C.5x = 5

x^3 + 6x^2 - 4x - 24
= x^2(x + 6) - 4(x + 6)
= (x^2 - 4)(x + 6)
= (x - 2)(x + 2)(x + 6)

The solution for 2x + y = 3 , x = 2y - 1 is x = 1 , y = 1 .
put x in equation 1
2(2y - 1) + y = 3
4y - 2 + y = 3
5y = 5
y = 5/5
y = 1
2x + 1 = 3
2x = 2
x = 2/2
x = 1

The solution for 3x + 2y - 5 = 0 , x = y + 10 is x = 5, y = -5 .
put equation 2 in equation 1
3(y + 10) + 2y - 5 = 0
3y + 30 + 2y - 5 = 0
5y = - 25
y = -5
x = -5 + 10
x = 5
