The difference between the roots of the quadratic equation x2−8x+p=0 is 6. Find p.

p=7

Step-by-step explanation:

x1+x2=8

2x+6=8

2x=2

x=1

c/a=c

x1*x2=c=p

x1*x2=7

p=7

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

you,
