Factorisation of 2x2 + 3x +1 is
Answer & explanation
Correct answer: option 2
2x2 + 3x + 1 = 2x2 + (2 + 1) x + 1
= 2x2 + 2x + 1x + 1
= 2x(x + 1) + 1(x + 1)
= (x + 1)(2x + 1)
Factorisation of 2x2 + 3x +1 is
Correct answer: option 2
2x2 + 3x + 1 = 2x2 + (2 + 1) x + 1
= 2x2 + 2x + 1x + 1
= 2x(x + 1) + 1(x + 1)
= (x + 1)(2x + 1)
