Express the polynomial as a product of linear factors. 3x^3+12x^2+3x-18
Marysya12 [62]

Answer:

f(x) =  3(x + 2)(x - 1)(x + 3)

Step-by-step explanation:

A logical first step would be to factor 3 out of all four terms:

f(x) = 3x^3+12x^2+3x-18 = 3(x^3 + 4x^2 + x - 6)

Roots of this x^3 + 4x^2 + x - 6 could be factors of 6:  {±1, ±2, ±3, ±6}.

I would use synthetic division here to determine which, if any, of these possibilities are actually roots of x^3 + 4x^2 + x - 6.  Let's try x = 1 and see whether the remainder of this synth. div. is 0, which would indicate that 1 is indeed a root of x^3 + 4x^2 + x - 6:

1    /    1    4    1    -6

                1    5    6

    ------------------------

          1     5    6    0

Yes, 1 is a root of x^3 + 4x^2 + x - 6, and so (x - 1) is a factor of x^3 + 4x^2 + x - 6.

Look at the coefficients of the quotient, which are   1, 5 and 6.

This represents the quadratic 1x² + 5x + 6, whose factors are (x + 2) and

(x + 3).

Thus, the given polynomial in factored form is:

f(x) = 3x^3+12x^2+3x-18 = 3(x + 2)(x - 1)(x + 3)

How do i solve the following question 2x + 3 = 9
Mademuasel [1]

Answer: x = 3

Step-by-step explanation: To solve for <em>x</em> in the equation you see here, our goal is to get <em>x</em> by itself.

Our first step will be to isolate the term containing <em>x</em> which in this case is 2x. To isolate 2x, we have to get rid of this +3 by subtracting from both sides of the equation.

On the left, +3 -3 cancels and we're left with 2x. On the right, 9 - 3 simplifies to 6.

So now we have the equation 2x = 6.

To get <em>x</em> by itself since it's being multiplied by 2, we just to divide by 2 on both sides of the equation. On the left, the 2's cancel and we're left with <em>x</em>. On the right, \frac{6}{2} simplifies to 3 so our answer is <em>x = 3</em>.

Answer:

H = 58, I = 71, J = 51

Step-by-step explanation:

Set all angles equal to 180

3x - 2 + 4x - 9 + 3x - 9 = 180

Then combine like terms

10x - 20 = 180

      + 20  + 20

10x = 200

/10     /10

x = 20

Then plug in for each angle

3 (20) - 2 = 58

4 (20) - 9 = 71

3 (20) - 9 = 51
