Whats the discriminant of xsquared+2x+6?

Question

i know that the formula is bsquared-4ac, but will someone tell me what the discriminant is?!!

HELP!!!!!!!!!!!!!!!! thanks

Answer 1

Consider equation:-
x² + 2x + 6 = 0
a = 1
b = 2
c = 6

Discriminant = b² - 4ac
Discriminant = 4 - 24
Discriminant = - 20

Answer 2

Firstly, you have to put all the 'X' on one side of the equation then put the numbers on the other side of the equation. Make sure to change the signs(+, -) while arranging it, for example, when placing the positive 6 on the other side of the equal sign, the positive 6 must change to negative six. Another example is when the positive X is placed on the other side of the equal sign, it must be changed to negative X. AN EXAMPLE: 6 + 2X = X - 6 2X - X = -6 - 6 Secondly, after the arrangement, calculate the equation. An example: 2X - X =-6 - 6 X = -12 In any kind of algebra, you must always remember these rules: (in simple addition and subtraction) A negative number + a negative number = you have to add the two numbers and the answer you get, put the minus sign before it( - 6 - 6 = - 12 ) A positive number + a negative number = you have to minus the two numbers and give the answer the sign of the larger number( - 6 + 3 = - 3 ) A positive number + a positive number = just add the two numbers and the answer you get will be a positive number ( 6 + 6 = 12 )

Answer 3

The discriminant IS b^2-4ac = 2^2-4(1)6) = 4-24 = -20

Answer 4

Well, you just said it. The discriminant is b² - 4ac, where a, b, and c come from the coefficients of a quadratic equation of the form:

ax² + bx + c = 0

In this case b is 2, a is 1, and c is 6. If you are asking what the discriminant is for, then it tells us the nature of the roots. If it is 0, there is one real root (or more accurately, two identical real roots). If it is positive, there are two distinct real roots. If it is negative, there are two imaginary (or complex) roots.

Answer 5

2^2 - 4*1*6 = 4-24 = -20 = 20*i^2 , i = root(-1)
which means complex root

Answer 6

in your quadratic,
a = 1
b = 2
c = 6

just plug those numbers into b^2 - 4(a)(c) and you'll get the discriminant.

-20

Answer 7

The discriminant is George Wallace, I believe.

Answer 8

[07]
x^2-2x+2=0
x^2-2x+1+1=0
(x-1)^2= -1
x-1=+-i {square rooting both sides]
x=1+-i ans
