Determine the factors of x2 − 8x − 12. (x − 6)(x 2) (x 3)(x − 4) prime (x 6)(x − 2)
Ivanshal [37]

The polynomial cannot be factored in because it exists prime. Since 112 exists not a perfect square number so we cannot estimate the factors of the given equation.

<h3>What is a quadratic equation?</h3>

In a quadratic equation ax² + bx + c = 0

when (b² - 4ac) exists a perfect square only then we can factorize the equation.

In the given equation x² - 8x - 12 we have to determine the value of

b² - 4ac

From the equation, we get b = -8 and c = -12

b²- 4ac = (-8)² - 4(1)(-12)

= 64 + 48 = 112

Since 112 exists not a perfect square number so we can not estimate the factors of the given equation.

zheka24 [161]
All you need to do is divide 1200by 25 to get the words per minute and then you can multiply that by 45 to get the answer 2160

Select TWO possible values for x in the equation x2=45.
kirill [66]

Answer:

3 \sqrt 5}  and -3 \sqrt 5}

Step-by-step explanation:

Given

x^2 = 45

Required

Determine the values of x

x^2 = 45

Take square root of both sides

\sqrt{x^2} = \±\sqrt{45}

x = \±\sqrt{45}

Expand 45 as 9 * 5

x = \±\sqrt{9 * 5}

Split the square root

x = \±(\sqrt{9} *\sqrt 5}

x = \±3 *\sqrt 5}

x = \±3 \sqrt 5}

This can be further split to:

x = 3 \sqrt 5} or x = -3 \sqrt 5}

Hence, the possible values of x are

3 \sqrt 5}  and -3 \sqrt 5}
