Choice D
To factor a quadratic equation ax^2+bx+c, find two factors of a and write them in a column, one up, one down. Then find two factors of c and write them in a column. multiply the factors diagonally and add up the products to make b. if the products do not make b, switch the factors up down and try again till you have a match.
in this case,
-1 and 3 are the factors of -3, -5 and 1 are the factors of -15, -1 times 1 is 1, 3 times -5 is -15, -1 and -15 make a sum of -16. so you have (-1x-5)(3x+1)
take the negative sign out you have -(x+5)(3x+1)
I hope I've made myself clear.

What is the limit of f(x) = 5 as x approaches ? (if an answer does not exist, enter dne.)
lions [1.4K]

The value of lim f(x) + g(x) in the information given is 2

<h3>How to calculate the value?</h3>

From the given information, the limit of f(x) is given as 5/4 and Lim g(x) = 3/4.

Therefore, lim f(x) + g(x)

= 5/4 + 3/4

= 8/4

= 2

Simplify 3(4x + 6) - 9x.<br><br> -15x + 18<br> 3x + 18<br> 3x + 6<br> 12x + 18 - 9x
Kamila [148]
Hi there!

To simplify this equation we first need to distribute.

(3)(4x) + (3)(6) + - 9x
= 12x +18 + - 9x

Next, combine like terms.

= 12x + 18 + - 9x
= (12x + - 9x) + (18)
= 3x + 18

In simplified form, 3 (4x + 6) - 9x is 3x + 18.

Hope this helps!
