-3x^2+5
- 3x + 5
Notice the ^ symbol for powers
2 + x
Notice you need parentheses
(2+x)/(3-
around the numerator and
x)
3 – x
denominator
Be sure to put parentheses
around the input: sqrt(x+3) is
OK, but sqrtx+3 or sqrt x+3 is
sqrt(x-5)
Vx – 5
not.
Parentheses keeps the x + 7
together as the power
3^(x+7)
3* +7
1
You may need nested
1/(x(x+1))
x(x + 1)parentheses

Unless the problem gives specific directions, any
algebraically equivalent expression is acceptable. For
example, if the answer was (x + 2)(x + 3), then
(х + 3)(х + 2) and (3 + z)(2 + х) would also be
acceptable.
