The model represents x2 â€" 9x 14. An algebra tile configuration showing only the Product spot. 24 tiles are in the Product spot
snow_lady [41]

The factors of the given model are (x+2) and (x+7)

Given the representation of the model expressed as;

x^2+9x+14

To get the factors, we will factorize the given quadratic function as shown:

g(x) = x^2+2x+7x+14

Group the functions to have;

g(x) = (x^2+2x) + (7x+14)\\

Factor out the GCF from both parenthesis:

g(x) = x(x+2)+7(x+2)\\g(x)=(x+2)(x+7)

Hence the factors of the given model are (x+2) and (x+7)

= 84 students × 8 ÷ 24 students

= 28 students

Hence, the students that brought a lunch box is 28

3x^2 -5x -2=0
Kipish [7]

Answer:

Step-by-step explanation:

1. Find two numbers that add to make the coefficient of x (in this case, -5) and that multiply to make the constant term multiplied by the coefficient of x^2 (in this case, -2 x 3 = -6)

Two numbers that work are -6 and +1

-6 x +1 = -6

-6 + -1 = -5

2. Split the middle term into the two numbers that you found.

3x^2 -6x +x -2 = 0

I've put the -6 on the left side because in our next step, when we factorise, it will be easier than having the numbers the other way around.

3. Factorise the left side by taking out common factors from each pair. The pairs I'm talking about here are '3x^2 and -6x', and 'x and -2'

3x (x-2) +1 (x-2) = 0

4. You now have two numbers both being multiplied by the term x-2. We can rearrange this equation to give us two brackets being multiplied by each other.

(3x + 1) (x-2) = 0

5. According to the Null Factor Law, if two terms are multiplied together and the result is 0, then one of those terms must be 0. Make both terms equal to 0 and solve each for x.

3x + 1 = 0              x-2 = 0

3x = -1                   x = 2

x = -1/3

6. The solutions to this equation are x = 2 and x = -1/3
