3 x. 3x²+x-3=0 Find the zeros

Mathematics
1 answer:
Tanya [424]3 years ago
3 0

Answer:

The zeroes of this polynomial are x_{1} \approx 0.847 and x_{2} \approx -1.180.

Step-by-step explanation:

Let 3\cdot x^{2}+x - 3 = 0, the quickest and most efficient approach to find the zeroes of this second order polynomial is by Quadratic Formula. For all a\cdot x^{2}+b\cdot x + c = 0, roots are determined by:

x_{1,2} = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a} (1)

Where a, b, c are coefficients of the polynomial.

If we know that a = 3, b = 1 and c = -3, then roots of the polynomial are, respectively:

x_{1,2} = \frac{-1\pm\sqrt{1^{2}-4\cdot (3)\cdot (-3)}}{2\cdot (3)}

x_{1,2} =\frac{-1\pm \sqrt{37}}{6}

The zeroes of this polynomial are x_{1} \approx 0.847 and x_{2} \approx -1.180.

Nonamiya [84]

Answer: n = -9

Step-by-step explanation:

-6n + 5 = 59 (Given)

-6n -5 = 59 - 5 (Subtraction Property of Equality)

-6n = 54 (Simplify)

\frac{-6}{-6} = \frac{54}{-6} (Division Property of Equality)

n = -9 (Simplify)

zaharov [31]

x +80 >-3x

add 3x to each side

4x+80 >0

 subtract 80 from each side

4x>-80

divide both sides by 4

x > -80/4

x>-20

In Angkor, Cambodia’s ancient city, a clever/A
stealth61 [152]

There is an error in clever.

<h3>What is the history of Angkor?</h3>

A dynasty of Khmer monarchs oversaw one of the biggest, wealthiest, and most advanced kingdoms in Southeast Asia's history from the city of Angkor, which served as the country's capital. The kings of Angkor ruled over a region that stretched from the tip of the Indochinese Peninsula northward to modern-day Yunnan province, China, and from Vietnam westward toward the Bay of Bengal from the last decade of the 9th century, when King Yashovarman I made Angkor his home, until the early years of the 13th century. These kings built a number of enormous structures throughout this time period to exalt themselves, their gods, and their capital city. They did this by using the enormous labour and financial resources at their disposal.
