1. Factorise the expression by taking monomial commonly out

20 r + 5

\(=\)

i (i r + i)

[Note: Insert the constant factor in the first box followed by variable factor]

30 d^{4} e^{2} - 20 d e^{3} + 50 d^{5} e

\(=\) \(de\)

(i d^{3} e - i e^{2} + i d^{4})

[Note: Insert the suitable coefficient in the answer box after factorising the expression]
