3w + 9x - 14y + 3w + 2x + 5y 2w + 2y + 7x + 4x - 11y + 4w
5x - 2y + 11W - 7V - 5w + 6x
3W – 3x – y + 3w + 14x – 8y
How many of them are equal?

Can someone factor this fully? my friend and i have two different answers and i would like to know if either of them is right. you in advance. a^2 - b^2 + 25 + 10a
