X^2 - 10x + 13 = 0 Solve quadratic equation In simplest form

Mathematics
1 answer:
Salsk061 [2.6K]3 years ago
8 0

Answer:

5 \pm 2\sqrt{3}

Step-by-step explanation:

A quadratic equation in the form

ax^2+bx+c=0

Can be solved by using the formula

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

In this problem, the equation is

x^2-10x+13=0

So, we have

a = 1

b = -10

c = +13

Using the equation above, we find:

x=\frac{-(-10)\pm \sqrt{(-10)^2-4(1)(13)}}{2(1)}=\frac{10 \pm \sqrt{48}}{2}=\frac{10 \pm 4\sqrt{3}}{2}= 5 \pm 2\sqrt{3}

Jim’s work evaluating 2(3/5)^3 is shown below.
Oksanka [162]

Answer:

Option b.

Step-by-step explanation:

we have

2(\frac{3}{5})^{3}

Evaluate

2(\frac{3}{5})^{3}=2(\frac{3^{3}}{5^{3}})\\ \\=2(\frac{27}{125})\\ \\=\frac{54}{125}

therefore

He did not apply the power to the denominator of 3/5

Consider triangle ABC. The legs have a length of 5 units each. What is the length of the hypotenuse of the triangle?
Korvikt [17]

Answer:

5\sqrt{2} units.

Step-by-step explanation:

We have been given that two legs of triangle ABC measures 5 units each. We are asked to find the length of the hypotenuse.

We will use Pythagoras theorem to solve for the hypotenuse of triangle ABC.

\text{Hypotenuse}^2=\text{Leg}^2+\text{Leg}^2

Substituting our given values in above equation we will get,

\text{Hypotenuse}^2=5^2+5^2

\text{Hypotenuse}^2=25+25

\text{Hypotenuse}^2=50

Upon taking square root of both sides of our equation we will get,

\text{Hypotenuse}=\sqrt{50}

\text{Hypotenuse}=\sqrt{25*2}

\text{Hypotenuse}=5\sqrt{2}

Therefore, the length of hypotenuse of triangle ABC is 5\sqrt{2} units.
