Question

Which expression is equivalent to

(2x+4)-(3x²+2x-1)?
A-3x² +3
B -3x² +5
C-3x² +4x+3
D -6x³-16x² - 6x+4

Answer 1

`\huge\boxed{\sf Option \ B}`

Explanation:

Given expression:

= (2x + 4) - (3x² + 2x - 1)

Solve parenthesis

= 2x + 4 - 3x² - 2x + 1

Combine like terms

= -3x² + 2x - 2x + 4 + 1

= -3x² + 5
