Please, I need help fast! n²-4-n-2 is equal to
A) (n-2)n
B) (n-2)(n+1)
C) (n+2)(n-3)
D) (n+2)n

And please write good explanation, not only the answer. Thank you!

C. (n+2)(n-3)

Step-by-step explanation:

n^2 - 4 - n - 2 = n^2 - n - 6

n = (-(-1) ± √(-1)^2 - 4(1)(-6))/(2(1)) = (1 ±√25)/2 = 6/2 or = -4/2

therefore, n = 3 or n = -2

therefore, n^2 - n - 6 = (n+2)(n-3)

This is a question on solving quadratic equations using a kind of formula. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
