Question

$1/(x(x+1))$ $x(x + 1)$ you may need nested parentheses
$5/3x+2/3$ $\frac{5}{3}x + \frac{2}{3}$ fractions are automatically formatted vertically when previewed
unless the problem gives specific directions, any algebraically equivalent expression is acceptable. for example, if the answer was $(x + 2)(x + 3)$, then $(x + 3)(x + 2)$ and $(3 + x)(2 + x)$ would also be acceptable.

a) enter the expression $2x^{2}+3x + 8$:
your input:
b) enter the expression $\frac{-8y + 6}{2y^{2}}$:
your input:
c) enter the expression $w^{2}+2sqrt{w + 1}$:
your input:
d) this last one will require you enter an equation: $p - 7 = \frac{4}{3}(t - 2)$
your input:

Explanation:

Step1: Match expression A to syntax

The expression $2x^2 + 3x + 8$ follows standard algebraic input syntax as shown in the examples, so it is typed directly.

Step2: Format fraction for B

For $\frac{-8y + 6}{2y^2}$, use the fraction syntax demonstrated in the examples.

Step3: Format radical for C

For $w^2 + 2\sqrt{w+1}$, use the standard syntax for square roots with parentheses for the radicand.

Step4: Match equation D to syntax

The equation $p - 7 = \frac{4}{3}(t - 2)$ follows standard algebraic input syntax, so it is typed directly.

Answer:

A) $2x^2 + 3x + 8$
B) $\frac{-8y + 6}{2y^2}$
C) $w^2 + 2\sqrt{w+1}$
D) $p - 7 = \frac{4}{3}(t - 2)$
