Question

F (X)=(3x-5) (3x+1)​

Answer 1

x1=-1/3,x2=5/3..............

Answer 2

It looks like you've provided a function F(x), which is a polynomial that can be simplified using the distributive property (also known as the FOIL method for multiplying binomials). The function F(x) is given by:

F(x) = (3x - 5)(3x + 1)

To simplify this, you can use the FOIL method, which stands for First, Outer, Inner, Last. This involves multiplying the terms in the first parentheses with the terms in the second parentheses and then combining like terms. Let's break it down step by step:

1. First: Multiply the first terms of both parentheses. = 3x * 3x = 9x^2

2. Outer: Multiply the outer terms of both parentheses. = 3x * 1 = 3x

3. Inner: Multiply the inner terms of both parentheses. = -5 * 3x = -15x

4. Last: Multiply the last terms of both parentheses. = -5 * 1 = -5

Now, add up all these terms:

F(x) = 9x^2 + 3x - 15x - 5

Combine the middle terms:

F(x) = 9x^2 - 12x - 5

So, the simplified form of the function F(x) is:

F(x) = 9x^2 - 12x - 5
