The roots of a quadratic equation are 5 and 2

. If one of the two factors of the equation is
x
−
5
, which expression could be a second factor?

2

2 x − − 3

2 x + 3

3 x − 2

3 x + 2

I think before we get to this answer we need to understand how roots of a quadratic equation works.

When a quadratic equation have 2 real roots such as a/b and c/d we can write the quadratic equation in factored form like this y or 0=(bx-a)(dx-c)

In this case we know the 2 roots are 5 and 2/3 and one of the factors is already x-5. so the other one according to the equation above that I wrote have to be 3x-2 and therefore the 3rd choice is correct.

Hope this helped you and if there is any questions about this please let me know in the comments.

stethere all not eveanp-by-step explanation:

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
