Use the graph of the polynomial function to find the factored form of the

irga5000 [103]

Answer:

A. (x - 3)(x + 3)

Step-by-step explanation:

From the graph the x-axis is crossed by the graph at different points which are;

x = 3 and x = -3

This means the solutions are : x = 3 and x =-3

The factors will form the following equation : (x - 3)(x + 3)

Answer:

So it gives you a little picture and tells you what would the question be if you had this graph.

Step-by-step explanation:

The correct answer would be B, find the area because the 4x + 3 is your length and 3x is your length, A = length * width. So the answer is B, find the area.

How do you factor 7x^{2}+29x+4

Gala2k [10]

When you have a coefficient in front of the "x^2" value, you have to multiply it by the end value (4)

so you want a set of integers that will add up to 29, by multiple to (7 x 4) = 28

The only numbers like that are 28 and 1, they add up to 29 and multiply to 29

Therefore, rewrite it like this 7x^2 + 28x + x + 4

and then factor out the 7x in the first two terms, to get this

7x(x+4) + x + 4, then factor out 1 in the latter two terms to get this:

7x(x+4) +1(x+4), then use grouping to combine what you've got:

The factors are: {{ (7x+1)(x+4) }}
