If p(x) = 42x^2 - 18 and p(x) = 832.5 then what are two possible values for x? (Explain how you got your answer or show work!)

Step-by-step explanation:

We are given the function:

Given that p(x) = 832.5, we want to determine two possible values of x.

We can substitute:

Adding 18 to both sides yields:

And dividing both sides by 42 yields:

We can take the square root of both sides. Since we are taking an even root, we will need plus/minus. Hence:

In conclusion, x = 4.5 or x = -4.5.

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
