Solve 4x − 2(x + 1) = 3x + 10. −12 12 −8 8
Dominik [7]
Original Equation: 4x - 2(x+1) = 3x + 10

Step 1: Use Distributive Property
4x - 2x - 2 = 3x + 10

Step 2: Combine Like Terms
2x - 2 = 3x + 10

Step 3: Solve
       2x - 2 = 3x + 10
     - 2x        -2x 
--------------------------------
      -2 = x + 10
    -10         -10
------------------------
    -12 = x

Which trinomial is the product of the expression below ? (2R-3) (R+12)
anastassius [24]
Answer:
2R^2 + 21R - 36

Explanation:
To answer this question, we will follow these steps:
1- expand the brackets
2- gather like terms

Steps are as follows:
(2R-3)(R+12) = 2R(R) + 2R(12) - 3(R) - 3(12)
                      = 2R^2 + 24R - 3R - 36
                      = 2R^2 + 21R - 36

Hope this helps :)

HelloI need some assistance with this question. I provided an answer, but it was incorrect. The images are enclosed.
ycow [4]

Given:

There are given that the zeroes and degrees of the polynomial:

\begin{gathered} \text{zeros:}-2,2,4 \\ \text{Degres:}3 \end{gathered}

Explanation:

From the concept of a polynomial:

A polynomial has a as zero if and only if (x -a) is a factor of the polynomial.

Then,

From the given polynomial:

f(x)=(x+2)(x-2)(x-4)

Then,

\begin{gathered} f(x)=(x+2)(x-2)(x-4) \\ f(x)=(x^2-2x+2x-4)(x-4) \\ f(x)=(x^2-4)(x-4) \\ f(x)=x^3-4x^2-4x+16 \end{gathered}

Final answer:

Hence, the polynomial is shown below:

f(x)=x^3-4x^2-4x+16
