What is the discriminant of the quadratic equation 7×^2+6×+3=0

Mathematics
1 answer:
Svetach [21]3 years ago
4 0

Answer:

-48

Step-by-step explanation:

For a general quadratic equation ax^2+bx+c=0, the discriminant = b^2-4ac.

So in your case, b^2-4ac = 6^2-(4 \cdot 7 \cdot 3) = 36-84 = -48

Which polynomial correctly combines the like terms and puts the given polynomial in standard form? one-thirdx 8x4 – two-thirdsx2
AURORKA [14]

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign. From the given option the option C correctly combines the like terms and puts the given polynomial in standard form which is,

8x^4-\dfrac{2}{3}x^2-\dfrac{2x}{3}\\

Hence the option C is the correct option.

<h3>Given information-</h3>

The given polynomial equation in the problem is,

\dfrac{1}{3} x+8x^4-\dfrac{2}{3}x^2-x

<h3>Polynomial equation </h3>

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.

In the above polynomial equation the variable are<em> x </em>and the highest power of the variable <em>x</em> is four.

Arrange the given polynomial equation in the power of the variable <em>x. </em>Thus,

8x^4-\dfrac{2}{3}x^2+\dfrac{1}{3} x-x

Make the group of the same power of the variable <em>x. </em>Therefore,

8x^4-\dfrac{2}{3}x^2+(\dfrac{1}{3} x-x)

8x^4-\dfrac{2}{3}x^2+\dfrac{x-3x}{3}\\

8x^4-\dfrac{2}{3}x^2-\dfrac{2x}{3}\\

From the given option the option C correctly combines the like terms and puts the given polynomial in standard form which is,

8x^4-\dfrac{2}{3}x^2-\dfrac{2x}{3}\\

Hence the option C is the correct option.

Identify each matrix A such that A^2 has identical diagonal elements?
Maksim231197 [3]

Answer:

The correct matrices are:

Matrix:

7 1 5

1 5 7

5 7 1

all diagonal elements of A^2 are: 7^2 + 1^2 + 5^2

Matrix:

9   18  27

27 -9  18

18  27 9

all diagonal elements of A^2 are: 9^2 + 27*18 + 18*27   or (-9)^2

Matrix:

8 1 6

6 8 1

1 6 8

all diagonal elements of A^2 are: 8^2 + 6*1 + 1*6
