In multiplying fractions, you multiply the numerators and denominators.
51 / 2 * 21 / 3
can be reduced as

(17 / 2) * (21 / 1)
357 / 2 --> This is the answer based on the given.

Assume that its a mixed fraction:
5 1/2 * 2 1/3
11/2 * 7/3
= 77 /6

Given: y = 3x - 4. For what value of x does y equal zero?

Greeley [361]

X = 4/3 because set y=0.
so 0=3x-4. add 4 to both sides so
4=3x. divide both sides by. 3 and you get x=4/3.

The factored form of the expression $x^2 - 9$ is $(x+3)(x-3)$

The expression x^2 + 9 has no real roots hence cannot be factored

Quadratic equations are equations with a degree of 2.

Given the quadratic function $x^2-9 \ and \ x^2+9$

For the function $x^2 - 9$

$=x^2-9\\=x^2-3^2$

Using the difference of two squares:

$a^2-b^2=(a-b)(a+b)\\x^2-3^2=(x-3)(x+3)$

For the expression x^2 + 9

The expression x^2 + 9 has no real roots hence cannot be factored
