\((4a – 9)(1.5a – 2) = = (4a)(1.2a) + (4a)(-2) + (-9)(1.5a) + (-9)(-2) = = 6a^2 – 8a – 13.5a + 18 = = 6a^2 –21.5a + 18\)

Multiply these polynomials: \(12ab(\frac{5}{6a} + \frac{1}{4ab^{2}})\)

Multiply the polynomials: \(6xy^2(1/2x - 2/3xy)\)

Please, multiply these polynomials: \((3t – 7)(1 + 3t^2)\)
