Question

# Write the product in standard form. (𝑥 − 7)^{2}

Hint:

### The methods used to find the product of binomials are called special products.

Multiplying a number by itself is often called squaring.

For example (*x* + 3)(*x* + 3) = (*x* + 3)2

## The correct answer is: 49

### (𝑥 − 7)^{2} can be written as (𝑥 − 7)(𝑥 − 7)

(𝑥 − 7)(𝑥 − 7) = x(x - 7) - 7(x - 7)

= x(x) + x(-7) - 7(x) - 7(-7)

= x^{2} - 7x - 7x + 7^{2}

= x^{2} - 14x + 49

Final Answer:

Hence, the simplified value of (𝑥 − 7)^{2} is x^{2} - 14x + 49.

^{2}- 7x - 7x + 7

^{2}

^{2}- 14x + 49

Final Answer:

Hence, the simplified value of (𝑥 − 7)

^{2}is x

^{2}- 14x + 49.
