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?
We know that when you submit questions you aren't free to use the right format to make the mathematical terms crystal clear. It is likely that you mean "x squared times 6 plus x squared times 2", which is clearer. You can factor out the "x squared" and you will see that you get "x squared times 8". You COULD mean (6x) squared plus (2x) squared, which would be different. 6x times 6x would equal x squared times 36, so your answer will be much different.
Which expression is equivalent to 64-x squared?
(x-8)(x+8)
What is x times -8x?
The equation "x times -8x" has equal to "-8x^2": "negative 8x squared". For example, x = 2 is "-8 * 2^2 = -8 * 4 = -32".
What does x times negative x equal?
It is: -x squared
X squared plus 8 times x squared?
x2 + 8x2 = 9x2
What is 3 squared times 7 squared times 8 as a composite number?
3 squared = 97 squared = 49Therefore, the sum is 9 x 49 x 8.This is equal to 3528.
What is 4 times x squared?
4x^2
Why does 2 times X plus one all squared equal 2 times X minus one all squared plus 8 times X?
Why don't you figure it out yourself
What does eight times eight equal with squared number?
8 x 8 = 64

Why does x times x equal x squared?
Yes, x times x equals x squared.
Is volume cubed or squared?
Cubed; Area is squared. Short version: No, squared is to the second power, cubed to the third. Long version: No- squared is X2 , or x times x. Cubed is X3, or x times x times x. For example: Squared: 22= 2x2= 4 Cubed: 23= 2x2x2= 8 So any 3-D object has to be X3. Area, which is 2-D, is squared.
8 squared add 5 squared?
13
What is 4 squared times 4 squared times 4 squared times 4 squared?
16 to the 4th power, or 16 x 16 x 16 x 16 = 65,536
What is the value of 8 squared?
8 squared = 8 x 8 = 64
