Answer 2

To find the value of the expression when a=3.6 and b=-2, simply substitute these values into the given expression and then perform the arithmetic calculations.

Let's plug in the values:

Expression = (2a - b) * (b - 3a) + (6a^2 + b^2)

a = 3.6 b = -2

Now, substitute the values:

(2 * 3.6 - (-2)) * ((-2) - 3 * 3.6) + (6 * 3.6^2 + (-2)^2)

Now, calculate each part step by step:

(2 * 3.6 - (-2)) = 9.2 ((-2) - 3 * 3.6) = -14.8 (6 * 3.6^2) = 77.76 (-2)^2 = 4

Now, continue with the expression:

9.2 * (-14.8) + (77.76 + 4)

Next, do the multiplication and addition:

-136.16 + 81.76

Finally, add the numbers:

-54.4

So, the value of the expression when a=3.6 and b=-2 is -54.4.
