What is the correct classification of x2 3x 8?
The expression x2 + 3x +8 is a quadratic trinomial.
Which two values of x are roots of the polynomial x2 plus 3x - 5?
x2 + 3x - 5 is an expression, not an equation. An equation may have roots, an expression does not. However, x2 + 3x - 5 = 0 is an equation and its roots are -4.1926 and 1.1926 (approx).
What is an example of a quadratic expression?
x2 + 3x + 4 This is quadratic because the highest exponent of x is 2, and it is an expression because there is no equals sign.
Which expression is a factor of x2 plus 2x-15?
x2+2x-15 = (x+5)(x-3) when factored
Which of the binomials below is a factor of this trinomial x2 plus 3x - 4?
The factors of the expression, x2 + 3x - 4 are (x + 4) and (x - 1). As no binomials have been shown then the answer can be checked against the missing expressions to see if there is a match.
