Multiply the binomials:

2a−9 and 3a + 4

Consider two binomials as 2a−9 and 3a + 4

Now,to get the product of two binomials 2a−9 and 3a + 4 we use the


distributive law i.e. (2a−9)×(3a + 4) = 2a(3a) + 2a(4)-9(3a)-9(4) = 6a2 + 8a-27a-36 = 6a2-19a-36


Therefore ,the product of 2a−9 and 3a + 4 is 6a2-19a-36.
