2x² + x - 15
= 2x² + 6x - 5x - 15
= 2x(x + 3) - 5(x + 3)
= (x + 3)(2x - 5)
2√2x³+125
= √2.√2.√2x³ + (5)³
= (√2x)³ + (5)³
= (√2x + 5)(2x²- 5√2x + 25)
6a² + a - 15
= 6a² + 10a - 9a - 15
= 2a(3a + 5) - 3(3a + 5)
= (3a + 5)(2a - 3)
x² – x – (a + 1)(a + 2)
= x² – x – (a + 1)(a + 1 + 1)
মনে করি, a + 1 = y
তাহলে প্রদত্ত রাশি,
x² – x – y(y + 1)
= x² – x – y²– y
= x²– y² – x – y
= (x + y)(x – y) – 1(x + y)
= (x + y)(x – 1)
= (x + a + 1){x – (a +1 ) – 1} [y এর মান বসিয়ে]
= (x + a + 1)(x – a – 1 – 1)
= (x + a + 1)(x – a – 2) (ans.)
