Given the equation (x+a)^2(x-2)=x^3+bx^2+12x-72 find a and b
GaryK [48]
Isolate the variable by dividing each side by factors that don't contain the variable.

a=-  \frac{ x^{2}-  \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2} ,-  \frac{ x^{2}+  \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2}

Solve for b by simplifying both sides of the equation then isolating the variabel.

b= \frac{12}{x}+ \frac{72}{ x^{2} }-2+2a- \frac{4a}{x}+ \frac{ a^{2} }{x}- \frac{2a^{z} }{ x^{2} }

Is o.123 rational or irrational
Allushta [10]

The definition of a rational number is:
Any number that can be made by building a fraction
using whole numbers.

You can make  0.123  that way.  Here's the fraction:   123/1000


It's also handy to know that any number that's completely
written down using digits ... and a fraction bar or a decimal
point if they're needed ... is a rational number.  This is not a
definition, and it doesn't cover all rational numbers, but it's
handy sometimes.

It's also handy to know that a decimal that has a set of digits
after the decimal point that repeats forever is a rational number,
even though you can't completely write it down (because it never
ends).
