Let f(x)=x^2+x−42 . enter the x-intercepts of the quadratic function

x = - 7, x = 6

Step-by-step explanation:

to find the x- intercepts set f(x) = 0, that is

x² + x - 42 = 0

To factor, consider the factors of - 42 which sum to + 1

These are + 7 and - 6

(x + 7)(x - 6) = 0

equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 6 = 0 ⇒ x = 6

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
