Factorize the expression 2s(^2) – 3st – 2t(^2).

  • A.
    (2s – t)(s + 2t)
  • B.
    (2s + t)(s – 2t)
  • C.
    (s + t)(2s – 1)
  • D.
    (2s + t)(s -t)
  • E.
    (2s + t)(s + 2t)
Correct Answer: Option B
Explanation

2s(^2) – 3st – 2t(^2)

= 2s(^2) – 4st + st – 2t(^2)

= 2s(s – 2t) + t(s – 2t)

= (2s + t)(s – 2t)
