Question

Factor:

2xy - xz + 2wy - wz

Which of the following is one of the factors?

(x + w)
(x - y)
(2x + y)

Answer 1

x + w

rearrange
2xy + 2wy -xz -wz
= 2y(x+w) -z(x+w)
= (x+w)(2y-z)

Answer 2

thanks do you think you can help me with sqrt 32x^3y^8 ?

Answer 3

ok

Answer 4

thanks

Answer 5

32^(1/2) x^(3/2) y^4

- take each part to the power 1/2

Answer 6

soo the answer is???
sorry but i have noo idea how to do that!!

Answer 7

that is the answer
it cant be simplified any further
the square root is the same as the number or letter to the power 1/2

sqrt4 = 4 ^ 1/2 = 2

sqrt x^3 = x^ (3 *1/2) = x^(3/2)
sqrt x^8 = x^(8 * 1/2) = x^4

Answer 8

you could use calculator to find sqrt 32 and write that if you like

so answer could be written as

5.6569 x^(3/2) y^4
