The editing cursor is shown as a blinking left arrow over the first character in

the line to be edited. As in an earlier exercise on line editing, we will use the

right and left arrow keys, š™, to move the cursor to the appropriate

place for editing, and the delete key, ƒ, to eliminate characters.

The following keystrokes will complete the editing for this case:

• Press the right arrow key, ™, until the cursor is to the right of the x

• Type Q2 to enter the power 2 for the x

• Press the right arrow key, ™, until the cursor is to the right of the y

• Press the delete key, ƒ, once to erase the characters y.

• Type ~„x to enter an x

• Press the right arrow key, ™, 4 times to move the cursor to the right

of the *

• Type R to enter a square root symbol

• Type „Ü to enter a set of parentheses (they come in pairs)

• Press the right arrow key, ™, once, and the delete key, ƒ, once,

to delete the right parenthesis of the set inserted above

• Press the right arrow key, ™, 4 times to move the cursor to the right

of the b

• Type „Ü to enter a second set of parentheses

• Press the delete key, ƒ, once, to delete the left parenthesis of the

set inserted above.

• Press ` to return to normal calculator display.

The result is shown next:

|R|, the absolute value, and SQ(b⋅R), the square of b⋅R. To see if we can

simplify this result, use FACTOR(ANS(1)) in ALG mode:

1 2 ... 62 63 64 65 66 67 68 69 70 71 72 ... 863 864
