Question

Which expressions are equivale (x²+3x-5)-(4x²+3x-6).

A. 5x²+6x-11
B. 5x²-6x+11
C) x²−x+1
D) 3x−1

Answer 1

To simplify the expression (x²+3x-5)-(4x²+3x-6), combine like terms and distribute the negative sign. The expression is equivalent to -3x² + x + 1.

Step-by-step explanation:

To simplify the expression (x²+3x-5)-(4x²+3x-6), we combine like terms and distribute the negative sign:

(x²+3x-5)-(4x²+3x-6) = x² + 3x - 5 - 4x² - 3x + 6

Next, we collect like terms and simplify:

x² - 4x² + 3x - 3x - 5 + 6 = -3x² + x + 1

Therefore, the expression is equivalent to -3x² + x + 1.
