What are the possible values of x in 8^2+4x = -1

Mathematics

jeyben [28]3 years ago

Answer:

So we can simplify this to

36+4x=-1

We can subtract by 64 on both sides. 4x = -37. Therefore the answer to this is

x = -37/4 = -9.25.

So the answer for x is -16.25. If you were trying to do a quadratic equation then sorry because you worded it wrong, and I solved properly.

This is the simplest form 4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2}).

<h2>Exponent</h2>

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2}  ) is an expression.

<h3>How to make it simple?</h3>

\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2}  )

On simplifying, we have

\rm 4\sqrt{2}  (x)^{\frac{3}{2}} * ( 3\sqrt{10} x^2 - \sqrt{5} x^{\frac{3}{2}})\\\\24\sqrt{5} x^{\frac{7}{2}}  - 4\sqrt{10}x^3\\\\4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2} )\\

This is the simplest form 4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2}).
