Which of the polynomial equations cannot be solved using the quadratic formula?

xxMikexx [17]

Answer:

The polynomial equation that cannot be solved using the quadratic formula: Option2: $x^2-2x^3-5=0$

Step-by-step explanation:

First of all we have to learn what a quadratic polynomial is.

A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.

The quadratic equation is of the form:

$ax^2+bx+c = 0$

From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.

Hence,

The polynomial equation that cannot be solved using the quadratic formula: Option2: $x^2-2x^3-5=0$

Solve x^2+4x=1 for x by completing the square

laila [671]

Answer:

x is approximately equal to 0.34 and -4.34

Step-by-step explanation:

$x^2 + 4x = 1\\x^2 + 4x + 4 = 5\\(x + 2)^2 = 5\\x + 2 = \sqrt{5} \\x = -2 + \sqrt{5}\\x \approx 0.34 \ and -4.34\\\\$

8th grade linear functions, will give brainliest if the steps are listed and explained :)))

Rom4ik [11]

Get the slope of the line using the two known points:

slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3

Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,

y - 6 1/4 = 3 (x - 3/4) ⇒ y = 3x + 16/4 = 3x + 4

Then for some given value of x, the third point has y-coordinate 3x + 4.

"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.
