Step-by-step explanation:
By the property of intersecting secants outside of a circle.
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2
Answer:

Step-by-step explanation:
John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.
40/500=320/x Cross multiply.
40x=160,000
Divide both sides by 40.
X=4,000
He needs his sales to be $4,000 to get $320 in commission.
