Help please! factoring polynomials

alexgriva [62]

Answer:

Step-by-step explanation:

you can use foil and the graph,

because you can see (in the graph) that the lines intersect at 1 and 4.

just use foil to help figure out which matches the slope.

something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be

-2 and -2, 2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.

X + one over two(6x − 4) = 6

Maurinko [17]

The given equation is:

x+ $\frac{1}{2} (6x-4)=6.$

Multiplying both sides by 2 we have:

2x + 6x − 4 = 12 [ multiplication property of equality]

Combining like terms:

8x-4=12

Adding 4 both sides

8x=16.[Addition property of equality]

Dividing both sides by 8:

x=2 [Division property of equality.]

The correct option in which the equation is solved are : B. Multiplication property of equality. 2. Combine like terms. 3. Addition property of equality. 4. Division property of equality.
