How do we find the factors of x2 – 64
sweet-ann [11.9K]

Answer:

The factors of x²-64 is equal to (x-8)(x+8).

Step-by-step explanation:

The given expression is:

x²-64

we know that, 8² = 64

So,

(x²-8²) = (x-8)(x+8) [As (a-b)(a+b) = a²-b²]

So, the factors of x²-64 i equal to (x-8)(x+8).

Solve the following system using substitution.
ziro4ka [17]

Answer/Step-by-step explanation:

3. By substitution method, let's substitute \frac{2}{3}x- 4 for y in the first equation.

Thus,

\frac{1}{3}x + 2(\frac{2}{3}x- 4) = 1

Solve for x

\frac{x}{3} + \frac{4x}{3} - 4 = 1

Add 4 to both sides

\frac{x}{3} + \frac{4x}{3} - 4 + 4 = 1 + 4

\frac{x}{3} + \frac{4x}{3} = 5

\frac{x + 4x}{3} = 5

\frac{5x}{3} = 5

Multiply both sides by 3

\frac{5x}{3}*3 = 5*3

5x = 15

Divide both sides by 5

x = 3

Now, substitute 3 for x in the equation.

y = \frac{2}{3}x- 4

y = \frac{2}{3}(3) - 4

y = 2 - 4

y = -2

The solution of the equation is x = 3, y = -2

4. Solving by elimination, let's try to eliminate the x-variable by adding both equation together.

3x - 2y = 11

-3x - y = 4

            -3y = 15  => (-3x +(-3x) = 0; -2y +(-y) = -3y; 11 + 4 = 15)

Divide both sides by -3 to solve for y

\frac{-3y}{-3} = \frac{15}{-3}

y = -5

Substitute -5 for y in the first equation to find x

3x - 2(-5) = 11

3x + 10 = 11

Subtract 10 from both sides

3x + 10 - 10 = 11 - 10

3x = 1

Divide both sides by 3

\frac{3x}{3} = \frac{1}{3}

x = \frac{1}{3}

The solution is x = \frac{1}{3}, y = -5
