Answer: B

x^{3}  (4x-1) (4x-1)

Step-by-step explanation:

Start with the given equation.

16^5 - 3x^3

Start out by factoring the GCF.  x^3 is the GCF of both terms:

x^3 (16x^2 - 1)

Use the different of squares method.:

a^2-b^2=(a+b)(a-b)

a^2=16\\b^2=1

Substituted the equations:

16^2-1^2=(a+b)(a-b)

Factor:

 16x^2-1^2=(4x+1)(4x-1)

Add GCF to the factor equation:

x^3(4x+1)(4x-1)

What are the x- and y-intercepts of the line 6x−y=10?
Elena-2011 [213]

Step-by-step explanation:

This equation is in Standard Form. To find the x and y intercepts, it is easier to convert it to slope-intercept form, or y = mx + b.

6x - y = 10

-y = -6x + 10

y = 6x - 10

In slope-interecept form, you can see that the y-int, b, is -10, the constant. To find x, set y to zero.

0 = 6x - 10

10 = 6x

10/6 = x

5/3 = x

Rhett is solving the quadratic equation 0= x2 – 2x – 3 using the quadratic formula. Which shows the correct substitution of the
Artemon [7]

Answer:

StartFraction 2 plus or minus StartRoot (negative 2) squared minus 4(1)(negative 3) EndRoot Over 2(1) EndFraction

Step-by-step explanation:

General quadratic equation: ax^2 + bx + c

where a is the coefficient of the quadratic term, b is the coefficient of the linear term and c is the independent term. Here the equation is: x^2 – 2x – 3, so a = 1, b = -2 and c = -3

Quadratic formula:

x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)}

Replacing

x = \frac{2 \pm \sqrt{(-2)^2-4(1)(-3)}}{2(1)}
