I'm assuming you want to factor this?
So first, use the distributive property.

10x^2+6xy-14xy-14y^2
10x^2-8xy-14y^2

Next take out the GCF of 2
2(5x^2-4xy-7y^2)

Next factor 
2(5x-7y)(x+y)

Whats the sum of 4 consecutive odd integers is 4 less than 100. what is the second largest integer?
Hunter-Best [27]

Let, the numbers = x,(x+2),(x+4),(x+6)

x+x+2+x+4+x+6 = 100-4 = 96

4x+12=96

4x = 84

x = 84/4 = 21

Second largest number, (x+2) = 21+2 = 23

So, your answer is 23

What is y+5x=6; x= -1,0,1
ExtremeBDS [4]
Y + 5x = 6

y + 5(-1) = 6
y + (-5) = 6
y - 5 = 6
y - 5 (+5) = 6 (+5)
y = 11
when x = - 1, y = 11

y + 5(0) = 6
y + 0 = 6
y + 0 (-0) = 6 (-0)
y = 6
when x = 0, y = 6

y + 5(1) = 6
y + 5 = 6
y + 5 (-5) = 6 (-5)
y = 1
when x = 1, y = 1


hope this helps
