Question

d^2 +48d + 128 splitting the middle term​

Answer 1

Answer:

middle term splitting is not possible because 128=2×2×2×2×2×2×2 and sum of any two grouping doesn't make 48

But if you make it 4d^2+48d+128, then middle term splitting is possible

4d^2+32d+16d+128

=4d(d+8)+16(d+8)

=(4d+16)(d+8)

=4(d+4)(d+8)
