Answer: [4x^2 - 14x + 5]
Step-by-step explanation: Use PEMDAS
First, combine the like terms within the parentheses:
The terms with (x^2) remain unchanged: (4x^2).
For the linear terms, add their coefficients: (-15x + x = -14x).
The constant terms are also added: (7 - 2 = 5).
the simplified expression: [4x^2 - 14x + 5]
