Question

simplify the following using (A + B) (A - B) = A² - B² (0.3−2a)(0.3+2a)​

Answer 1

Answer:

The simplified form is $0.09 - 4a^{2}$

Step-by-step explanation:

In the above-given, we have been stated that we have to take into use the identity which is mentioned below and then calculate the respective value of the given sum:

(0.3−2a)(0.3+2a)​

For this we need to use the following given:

$(A + B) (A - B) = A^{2} - B^{2}$

here we have, A = 0.3 and B = 2a

therefore, (0.3−2a)(0.3+2a)​

= $(0.3)^{2} - (2a)^{2}$

= $0.09 - 4a^{2}$

Hence we have the answer to be $0.09 - 4a^{2}$
