Answer:
[tex]x=3,\frac{5}{2}[/tex]
General Formulas and Concepts:
Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
Standard Form: ax² + bx + c = 0
Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
-2x² + 11x = 15
-2x² + 11x - 15 = 0
a = -2, b = 11, c = -15
Step 2: Solve for x
