What is 8 - 2x -12?
It is an expression that can be simplified to -4-2x
Which of the following verbal expression represents the algebraic expression 2x-8?
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
Which expression is a factor of x2 plus 2x-15?
x2+2x-15 = (x+5)(x-3) when factored
How would the expression x cubed minus 8 be rewritten using the difference of cubes?
Answer: (x - 2)(x² + 2x + 4)Factor the difference of cubes:a³ - b³ = (a - b)(a² + ab + b² )note 8 = 2³ = 8 ⇒ b = 2 , with a = xSox³ - 8= x³ - 2³= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
How do you factor the expression x cubed minus 8?
(x3 - 8) is factored thus: (x - 2)(x2 + 2x + 4) The easiest way to do this is to remember the formula: (a3 - b3) = (a - b)(a2 + ab + b2)
