What is the simplified expression of: 3a - a x 4a + 2a? And what rule do we use to carry out the simplification?
To simplify the expression we use B(rackets)I(nidices)D(ivision)M(ultiplication)A(ddition)S(subtraction) in this specific order.Hence, here the first thing we need to do is identify each element of BIDMASS. Here the first element is M, and then A, and S.M: (ax4a)A: 3a+2aS: 5a-4a2Hence, the simplification will be: 5a-4a2
