Chapter 0: Problem 45

Find each product. $$(x-3)^{2}$$

Short Answer

Expert verified
The product of \((x-3)^{2}\) is \(x^{2} - 6x + 9\).

Step by step solution

01

Understand the Binomial Squared

A binomial squared \((x-a)^{2}\) can be rewritten as \((x - a)(x - a)\). We can apply this to our case, and rewrite \((x-3)^{2}\) as \((x - 3)(x - 3)\).
02

Using the FOIL Method

Next, apply the First, Outside, Inside, Last (FOIL) method to multiplied the expanded binomials. This means multiplying the first terms together, then the two terms on the outside, then the two terms on the inside, and finally the last two terms. So it becomes \(x * x - 3 * x - 3 * x + 3 * 3\).
03

Simplify the Result

Now simplify the resulting expression. The obtained result \(x * x - 3 * x - 3 * x + 3 * 3\) simplifies to \(x^{2} - 6x + 9\).

Place the correct symbol, \(>\) or \(<,\) in the shaded area between the given numbers. Do not use a calculator. Then check your result with a calculator. $$\text { a. } 3^{\frac{1}{2}} \square 3^{\frac{1}{3}}$$ $$\text { b. } \sqrt{7}+\sqrt{18} \square \sqrt{7}+18$$

Explain how to simplify \(\sqrt{10} \cdot \sqrt{5}\)

Determine whether each statement makes sense or does not make sense, and explain your reasoning. When I use the definition for \(a^{\frac{m}{n}}\) I usually prefer lo first raise \(a\) to the \(m\) power because smaller numbers are involved.

Explain how to convert from scientific to decimal notation and give an example.

Explain how to add \(\sqrt{3}+\sqrt{12}\)
