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.

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

Hopefully i helped ^.^ Mark brainly if possible

PLEASE HELP THANK YOU SO MUCH

Hi there!

The answer is B.

Since the middle length of the kite is 3 + 3 (which is 6), we find the area of both triangles and add them up.

6 × 10 ÷ 2 = 60 ÷ 2 = 30

6 × 20 ÷ 2 = 120 ÷ 2 = 60

30 + 60 = 90

The answer is B.

Hope this helps!

A rectangular football field is 64 meters wide and 100 maters long. A player runs from one corner of the field in a diagonal lin

Dimas [21]

Answer:

119 or 118.726577

Step-by-step explanation:

We should use the Pythagorean Theorem to solve this problem.

a^2+ b^2=c^2

64^2+100^2=c^2

4096+10000=14096

c^2=14096

c=\sqrt{14096}14096

And the root of 14096 is 118.726577.

So the Answer is About 119 meters, or 118.726577

hope this helps!
