Question

The value of (1.5a + 2b)² is​

Answer 1

Answer: $2.25 a^{2} + 4 b^{2} + 6 ab$ is the value of given polynomial.

Given: We are given (1.5a + 2b)²

To Find: We need to find the value of the given factored form of polynomial.

Step-by-Step Explanation: Let's look at the definition of polynomial

Definition of polynomial: More than two terms in the form of an expression are called a polynomial.

So, the given polynomial is in the factored form, we have to find its original form.

We know the formula for solving whole square of a sum:

$(a+b)^{2} = a^{2} + b^{2} + 2ab$

Step 1: Applying the formula to solve it:

= $(1.5a)^{2} + (2b)^{2} + 2*(1.5a)*(2b)$

 = $2.25 a^{2} + 4 b^{2} + 6 ab$
