Question

Select the expression that is equivalent to (x-3)^2

Answer 1

Answer:

C. $x^2-6x+9$

Step-by-step explanation:

We have the expression $(x-3)^2$ we can rewrite it as:

$(x-3)^2=(x-3)(x-3)$ and solve it with distributive property or we can use the formula to multiply a binomial by itself. The formula is:

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

or

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

Then:

$(x-3)^2=x^2-2.x.3+3^2\\(x-3)^2=x^2-6x+9$

The correct option is C. $x^2-6x+9$

Answer 2

The answer is C. X^2-6x+9
