B) Factorise
Factorise y2 + 2y - 24

(y + 6)(y - 4)

Step-by-step explanation:

Factor the following:

y² + 2y - 24

The factors of -24 that sum to 2 are 6 and -4.

So,

y² + (6 - 4)y -24

y² + 6y - 4y - 24

y(y + 6) - 4(y + 6)

(y + 6)(y - 4)

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
