The discriminant of the given quadratic expression is -7
This quadratic expression can't be factored because its discriminant is less than zero.
(x2+3x-4) (x-4)
x2 + 3x + 7 = 5 ∴ x2 + 3x + 2 = 0 ∴ (x + 1)(x + 2) = 0 ∴ x ∈ {-2, -1}
x2 + 3x + 2 factors into (x + 1) (x + 2)
The discriminant of the given quadratic expression is -7
The expression x2 + 3x +8 is a quadratic trinomial.
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
This quadratic expression can't be factored because its discriminant is less than zero.
x2 + 48x + 320
(x2+3x-4) (x-4)
x2 + 3x + 7 = 5 ∴ x2 + 3x + 2 = 0 ∴ (x + 1)(x + 2) = 0 ∴ x ∈ {-2, -1}
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.
x2 + 3x - 40 = (x + 8)(x - 5)
3 - 3x + x2 - x3 = (1 - x)(x2 + 3)
x3 + x2 - 3x - 3 x(x2 + x - 3) - 3
(x2 + 3x + 5)(x2 - 3x + 4)
