What is the solution to (x+6)(x+2)=60

Citrus2011 [14]

Distribute to eliminate the parenthesis

x^2 + 2x + 6x + 12 = 60

Combine like terms

x^2 + 8x + 12 = 60

Subtract 60 from both sides

x^2 + 8x - 48 = 0

Factor the equation

(x+12)(x-4)=0
x+12=0
x+4=0

x= -12 and -4

How do I graph the parabola?

scoundrel [369]

First of all, find a program or a calculator that will give you the answer. Then you'll know how to make your table. I recommend Desmos. I have inserted the final graph for you.

Make up a table for this graph. Put the lowest point as the central entry in your graph.

x y
-4
-3
-2
-1
0
Now fill in the y values.

x y
-4 1
-3 -3.5
-2 -5
-1 -3.5
0 1

You can use the outline of the parabola and then mark the outline with the points in the table.
