Simplify:
(9x3+2x2−5x+4)−(5x3−7x+4)
AAAaannndd the bot gets it wrong yet again!
(9x^3+2x^2−5x+4)−(5x^3−7x+4)
4x^3 + 2x^2 + 2x
2x(2x^2 + x + 1)
We can simplify the given expression by combining like terms.
(9x^3 + 2x^2 - 5x + 4) - (5x^3 - 7x + 4)
= 9x^3 - 5x^3 + 2x^2 - 5x - 7x + 4 - 4 (distributing the negative sign)
= 4x^3 + 2x^2 - 12x (combining like terms)
Now, we can factor out 2x from the expression to get the final answer in factored form:
= 2x(2x^2 + x - 6)
