What does x times negative x equal?
Well, honey, when you multiply x by negative x, you get negative x squared. It's like math's way of saying "two wrongs don't make a right, they make a negative." So, in this case, x times negative x equals negative x squared.
X squared plus 9 squared equals 12 squared?
X = √63
How do you work out numbers squared?
A number squared is just that number times itself. For example four squared is four times four equals sixteen (42 = 4 x 4 = 16).
How do you solve this problem what is the value of the expression 2x squared plus 3xy - 4y squared when x equals 2 and Y equals 4?
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
6x squared plus 2x squared equals?
Oh, dude, when you add 6x squared and 2x squared, you get 8x squared. It's like combining 6 apples with 2 apples and ending up with 8 apples. So, in math terms, 6x squared plus 2x squared equals 8x squared. Easy peasy!
Does x times x equal 2x?
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
What are the factors for x2?
X squared equals x times x.
What is x squared plus 25 times y squared equals 50?
It is the Cartesian equation of an ellipse.
X to the second power equals?
X to the 2nd power is simply X squared, or X times X.
What does six squared mean?
Six 'squared' means six times itself (6 x 6), which equals 36.
What does x times negative x equal?
Well, honey, when you multiply x by negative x, you get negative x squared. It's like math's way of saying "two wrongs don't make a right, they make a negative." So, in this case, x times negative x equals negative x squared.
X squared plus 9 squared equals 12 squared?
X = √63
Is fx equals x x equals 5 a linear equation?
no, because xx=x squared, and x squared is not linear
Why is brayani wrong when she says when x equals 3 the value of 4x squared is 36?
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
What is Sin squared x - Cos squared x divided by 1 - Tan squared x equals cos squared x?
22
