Question

The product of (a – 2c)(a – 2c ) =​

Answer 1

Answer:

a²-2ca-2ca+4c²

=a²-4ca+4c²

Answer 2

Given data,

The given equation is $(a -2c)(a -2c )$

The given equation can be written as $(a -2c )^{2}$

As we know the formula for identity

$(a-b)^{2}$

The formula can be written as

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

Here,

the value of $a=a$

the value of $b=2c$

Substitute these values in the formula.

We get,

$(a -2c )^{2}=a^{2} +(2c)^{2} -2(a)(2c)$

$(a -2c )^{2}=a^{2} +4c^{2} -4ac$

Therefore, the product of $(a -2c)(a -2c )$ is $a^{2} +4c^{2} -4ac$
