Step-by-step explanation:
abx^2-aby^2+xya^2-xyb^2
abx^2+xya^2-aby^2-xyb^2
ax(bx+ya)-yb(ay+xb)
ax(bx+ya)-yb(xb+ay)
(ax-yb) (bx+ya)

Answer:
17 packets
Step-by-step explanation:
So Tanya needs 130 chocolate bars.
But there is 8 in each packet.
So,
130 ÷ 8 = 16.25
16 packets
As you can see, there is a quarter left of chocolates that she needs (0.25). So what she can do is buy 1 more packet then give the quarter of that packet to the children.
So 16 + 1 = 17 packets
vertex (1,-1) axis of symmetry is x=1, domain all real numbers (i think neg ys) range y is less equal than -1, y increases as x less 0 bug IMO x decreases
