Multiply the polynomials:(i)(2.5a−0.5b) and (4b2−8ab)(ii)(19)a2+bc−15 and (47)b2+ab+10

Multiply the polynomials:(i)(2.5a−0.5b) and (4b2−8ab)(ii)(19)a2+bc

1.	Multiply the polynomials:(i)(2.5a−0.5b) and (4b2−8ab)(ii)(19)a2+bc−15 and (47)b2+ab+10
Answer» Multiply the polynomials: $(i) (2.5 a - 0.5 b) a n d (4 b^{2} - 8 a b)$ $(i i) (\frac{1}{9}) a^{2} + b c - 15 a n d (\frac{4}{7}) b^{2} + a b + 10$
