Question

Solve quadratic equations by two main methods: factoring and using the quadratic formula.
2m²-m-15=0 (this one is to be factored)
2y²-3y-6=0 (solve using quadratic formula).
• For the factoring problem, be sure you show all steps to the factoring and solving. Show a check of your solutions back into the original equation.
• For the Quadratic Formula problem, be sure that you use readable notation while you are working the computational steps.
• Present your final solutions as decimal approximations carried out to the third decimal place. Due to the nature of these solutions, no check is required.
• Incorporate the following four math vocabulary words into your discussion. Use bold font to emphasize the words in your writing (Do not write definitions for the words; use them appropriately in sentences describing your math work.):
o Quadratic formula
o Factoring
o Completing the square
o Discriminant
