Problem 144 of 7
Determine whether 2x^2+7x+3 is factorable over the integers and explain.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
test factor pairs and recognize when another method is needed.
Hidden until you reveal it.
Quadratic must be in standard form with integer coefficients.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Check factor pairs for the constant and leading coefficient.
2. Compare products and sums to the quadratic coefficients.
3. State whether integer factoring works or another method is needed.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using decimal roots as evidence of integer factorability.
