Simplify
(2x - 5)^2
4x^2 - 20x + 25
To simplify (2x - 5)^2, you can use the formula for squaring a binomial.
The formula is (a - b)^2 = a^2 - 2ab + b^2.
In this case, a is 2x and b is 5.
Substituting those values into the formula, we get:
(2x - 5)^2 = (2x)^2 - 2(2x)(5) + (5)^2
Expanding further, we have:
= 4x^2 - 20x + 25
So, (2x - 5)^2 simplifies to 4x^2 - 20x + 25.
