Question

4) Factorise: y3 + 2y2 – 48y​

Answer 1

Answer:

y(y2+2y-48)

Step-by-step explanation:

y3=y×y×y

2y=2×y×y

48y=2×2×2×2×3×y

=y(y2+2y-48)

Answer 2

Step-by-step explanation:

• y^3 + 2y^2 -48y
• y(y^2 + 2y -48 )
• y ( y^2 +(8-6)y -48 )
• y ( y^2 +8y-6y -48)
• y( y(y+8) -6(y+8))
• y {(y+8)(y-6) }
• y (y+8)(y-6)
• (y^2+8y) (y-6).
