factor 4a^2-b^2-2a+b

Answers

Answer 1

Answer:Equation at the end of step 1

STEP

4a2 - b2

Simplify ————————

2a - b

Trying to factor as a Difference of Squares:

2.1 Factoring: 4a2 - b2

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : a2 is the square of a1

Check : b2 is the square of b1

Factorization is : (2a + b) • (2a - b)

Canceling Out :

2.2 Cancel out (2a - b) which appears on both sides of the fraction line.

Final result :

2a + b

Answer:

√35i

Step-by-step explanation:

i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.

Answer:

We know that √-1 = i, where "i" is the imaginary unit

± √(-35) = ± √(35) i

± √(35) i is the right answer.

Find the slope of the line on the graph below:
Slope

Answers

Answer:

The slope of the line on the graph is [tex]\frac{3}{2}[/tex].

Step-by-step explanation:

The slope of a line can be found with [tex]\frac{\Delta y}{\Delta x}[/tex]. The points (3,2) and (-1,-4) lie on the line, so we can subtitute [tex]\Delta y = -4 -2 = -6[/tex] and [tex]\Delta x = -1-3 = -4[/tex] to see that the slope equals [tex]\frac{-6}{-4} = \frac{3}{2}[/tex]. This answer makes sense because the slope is going up when [tex]x[/tex] becomes larger (the slope is positive), and we travel more in the [tex]y[/tex]-direction than in the [tex]x[/tex]-direction (the slope is greater than 1).

Use the formula:
y2-y1 divided by x2-x1 aka delta y over delta x

(basically the change in y divided by the change in x)

so it would end up being:
-4 minus 3 divided by -1 minus 2

which equals 7/3 or 2.3333
