How many times does a porabola cross the x-axis when using imaginary numbers?

NONE If both roots are imaginary, the means the parabola does NOT cross the x-axis at all. The place where a function crosses the x- axis has the coordinate (x,0) for some value of x. That means if you plug in x to the function or polynomial, you get 0. This is equivalent to saying that x is a root of the polynomial. But if the only roots are imaginary, there will be no point (x,0) for any real number x.

What is a difference between an imaginary and an irrational number?
An irrational number is a subset of the set of real numbers. So a rational number is an number which can be expresses as a ratio (fraction) of a/b where a is any integer, and b is any nonzero integer. Note that integers are real numbers. So irrational numbers are all real numbers which are not rational numbers.Note that all of the numbers so far are real numbers. Now for imaginary numbers. Look at the KhanAcademy video or MathsIsFun.Take a number -1 and try to square root. Note that (-1) times (-1) equals positive 1. So we created a number i, which when squared equals -1. This is the imaginary unit number. Now you can take any real number, and multiply that by i to get any imaginary number.
Two times a number plus three times another number equals 13 the sum of the two numbers is 7 what are the numbers?
(-8,1)
The sum of two numbers is 84 One number is three times the other Find the numbers?
The numbers are 21 and 63.
The difference of two positive numbers is 16. One number is 3 times the other. Find the two numbers?
If the higher is 3 times the lower, the difference must be twice the lower so the numbers are 8 and 24.
What two numbers multiply to get 104 and add to 56?
160
Is the product of two imaginary numbers always an imaginary number?
If you are talking about pure imaginary numbers (a complex number with no real part) then no. Example: bi times ci where b and c are real numbers equals b*c*i² = b*c*(-1) = -b*c, which is a real number, because b & c & -1 are all real numbers. If you're talking about multiplying two complex numbers (a + bi)*(c + di), then the product will be complex, but it could be real or imaginary, depending on the values of a, b, c, & d.
How do you do cross cancellation?
Divide the numbers that are diagonal from each other, but there are times when this does not work.
What is 4 times the square root of 3 times 2?
4 times the square root of 5. it's undefinable so that's the most you can simplify it without using imaginary numbers
What is the meaning of coefficients?
3xy -- 3 is the coefficient of the variables x and y All these are being multiplied -- 3 times x times y Definition of coefficient -- A numerical value multiplied by a variable. Numerical values are not only whole numbers, but can be fractions (rational numbers), negative numbers, irrational numbers and imaginary numbers.

Are unicorns imaginary animals from Medieval Times?
Unicorns have been around for a long time, so they were around in medieval times, but no, they were not and are not just imaginary.

What times what equals -10?
It could be any of these, or more (considering fractions or imaginary numbers): 1 * -10 -1 * 10 2 * -5 -2 * 5
How do you find the square root of negative numbers?
For most school mathematics, negative numbers do not have square roots. This is because a negative number multiplied by itself is a negative times a negative and so is positive. When (if) you study advanced mathematics, you will learn that there is a solution and this falls within the realms of complex mathematics and imaginary numbers.
Math questions with the answer 336?
24 times 14 equals 336 48 times 7 equals 336 there is an infinite number of ways to get to 336. definitely when you include imaginary numbers
Why does negative 2 times negative 2 equal 4?
Because when two negative numbers times each other the answer is always a positive. It is a maths term and it is true (cross my heart).
What 2 numbers times each other equal to -126 and will add up to - 9?
