Factor x2 – 3x – 28.
wariber [46]

Values needed to complete the X diagram are:

On top -28, On the bottom: -3 and On the sides: -7 and 4.

<h3>What do you mean by factorization?</h3>

An algebraic expression is factorised when it is written as the product of its factors.

The given equation is :

F(x) = x²-3x-28

finding factors,

=  x²-7x+4x-28

= x(x-7) +4(x-7)

= (x-7)(x+4)

Given general equation is ax²+bx+c,

on comparing with  x²-3x-28

a = 1

b = -3

c = -28

ac = 1*(-28) = -28

Natalka [10]
Hey there! :) How are you? Basically what you said is right. 

Question 1: There are 16 oz (ounces) in a pound, so we do 64/16= 4 lbs (pounds). 

Question 2: If Jack has 3 pounds of pasta, that would mean he has 48 ounces, since 1 pound is 16 oz, so 16*3= 48 ounces. 

Hoped I helped! Have a nice day, and keep smiling! :)
