Chapter 0: Problem 22

Find each product. $$(x-1)(x+2)$$

Short Answer

Expert verified
The product of \( (x-1)(x+2) \) is \( x^2+x-2 \).

Step by step solution

01

Apply Distributive Property 1st time

First, you should multiply \( x \) from the first brackets by both terms in the second brackets, which results in \( x^2+2x \).
02

Apply Distributive Property 2nd time

Secondly, you should multiply \( -1 \) from the first brackets by both terms in the second brackets, which results in \( -x-2 \).
03

Combine like terms

Now, combine all the obtained terms. This gives \( x^2+2x-x-2 \). Combining like terms, you get \( x^2+x-2 \).

A football was kicked vertically upward from a height of 4 feet with an initial speed of 60 feet per second. The formula $$h=4+60 t-16 t^{2}$$ describes the ball's height above the ground, \(h,\) in feet, \(t\) seconds after it was kicked. Use this formula to solve Exercises \(19-20 .\) What was the ball鈥檚 height 3 seconds after it was kicked?
