No. 2x means 2 times x. For example, 210 = 1024, while 2 x 10 = 20.
3x^2 + x + 2x^2 = 5x^2 + x
The expression ( x^2 + 2x^2 ) can be simplified by combining like terms. Adding ( x^2 ) and ( 2x^2 ) results in ( 3x^2 ). Therefore, ( x^2 + 2x^2 = 3x^2 ).
No, -2x is not the same as x - 2. The expression -2x represents the product of -2 and x, while x - 2 represents the value of x decreased by 2. They are different algebraic expressions and will yield different values for most values of x.
The expression ( 2x^2 + x^2 ) can be simplified by combining like terms. Since both terms contain ( x^2 ), you can add the coefficients: ( 2x^2 + x^2 = 3x^2 ). Therefore, the simplified expression is ( 3x^2 ).
2x^8 x 3x^2 x -4x = -24x^11
3x^2 + x + 2x^2 = 5x^2 + x
The expression ( x^2 + 2x^2 ) can be simplified by combining like terms. Adding ( x^2 ) and ( 2x^2 ) results in ( 3x^2 ). Therefore, ( x^2 + 2x^2 = 3x^2 ).
(x^2 - 2x + 2)(x^2 + 2x + 2)
The power law of indices says: (x^a)^b = x^(ab) = x^(ba) = (x^b)^a → e^(2x) = (e^x)² but e^x = 2 → e^(2x) = (e^x)² = 2² = 4
2(x + 2)(x - 2)(x2 + 2x + 4)(x2 - 2x + 4)
2x^2
No, -2x is not the same as x - 2. The expression -2x represents the product of -2 and x, while x - 2 represents the value of x decreased by 2. They are different algebraic expressions and will yield different values for most values of x.
Assuming that he quadratic is 2x^2 + x - 15, the quotient is 2x - 5.
The expression ( 2x^2 + x^2 ) can be simplified by combining like terms. Since both terms contain ( x^2 ), you can add the coefficients: ( 2x^2 + x^2 = 3x^2 ). Therefore, the simplified expression is ( 3x^2 ).
No. x squared is x times x, whereas 2x is x + x.
2x^8 x 3x^2 x -4x = -24x^11
(x - 2)(x + 2)(x2 - 2x + 4)(x2 + 2x + 4)
