Question

What is the simplest form of the expression 2x(x − 6) − 7x2 − (13x − 3)?

Answer 1

We have the following expression:
 2x (x - 6) - 7x2 - (13x - 3)
 We will solve the expression step by step.
 We solve the parentheses:
 2x ^ 2 - 12x - 7x ^ 2 - 13x + 3
 Now we add similar terms:
 x ^ 2 (2-7) + x (-12-13) + 3
 Rewriting:
 -5x ^ 2 - 25x + 3
 Answer:
 The simple form of the expression is:
 B.) -5x2 - 25x + 3
