Is it possible to find three solutions of the equation x3 plus 2x2 plus 3x plus 6 equals 0 Explain why or why not?
The variable term, X^3, is a third order polynomial term and will render three solutions, though one of those may be zero.
Factor 2x squared plus 6x - 8 equals 72?
2x2 + 6x - 8 = 72 ∴ 2x2 + 6x + 64 =0 ∴ x2 + 3x + 32 = 0 This can not be factored, as x is not equal to any integer. Using the quadratic equation, we find that: x = -3/2 ± √119 / 2i
