Henrietta solved a rational equation by multiplying both sides by $3x^{2}(x+2)$ .She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.

Henrietta can have got rid of denominator and then use the distributive rule .

So the first option

A:She could use the least common multiple of the denominator is right

If (a-bi)^2 = 13 - 12i, what is the product of a and b?

VARVARA [1.3K]

Answer:

$\large \boxed{\sf \ \ \ a\cdot b= 6 \ \ \ }$

Step-by-step explanation:

Hello,

$(a-bi)^2 = 13 - 12i\\\\ a^2+(bi)^2-2abi = 13-12i\\\\a^2-b^2-2abi=13-12i$

Imaginary term must be the same so

-2ab=-12

2ab = 12

ab = 12/2 = 6

So the product of a and b is 6

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
