Simplify (x-2)(x+6) using grouping and write the result expression in standard form

x^2 + 4x - 12.

Step-by-step explanation:

(x - 2)(x + 6)

= x(x + 6) - 2(x + 6)

= x^2 + 6x - 2x - 12

= x^2 + 4x - 12.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
