Can X3 + a x + b have more than one real solution?

Call the solutions a and b. Then by Rolle’s Theorem we know that 3 x 2 + a = 0 for some c in ( a, b), but with a > 0 this is impossible. Hence x 3 + a x + b cannot have more than one real solution. Thanks for contributing an answer to Mathematics Stack Exchange!

How do you find the opposite of Ax+2x?

Use the distributive property to multiply a+2 by x. Use the distributive property to multiply a+ 2 by x. To find the opposite of ax+2x, find the opposite of each term. To find the opposite of ax+2x, find the opposite of each term. Subtract x^ {2} from both sides. Anything subtracted from zero gives its negation. Subtract x2 from both sides.

What is the derivative of 3x^2 + a?

The derivative of the function is 3 x 2 + a, Since the derivative is always positive the function is increasing and thus injective. So it cannot repeat values, in particular it cannot have two roots.
