What is the difference of the polynomials (5x^3+4x^2)-(6x^2-2x-9)

1 answer:

5 0

So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.

Surface Area of a sphere, A grapefruit with C = 14cm.

9966 [12]

Surface area SA: $4\pi r^2$
Circumference C: $2\pi r$ dividing this you get $7=\pi r$ and $r= \frac{7}{\pi}$

Now let's input the radius $r$ into the Surface area formula...
$4\pi r^2\rightarrow 4\pi(\frac{7}{\pi})^2=4\pi(\frac{49}{\pi^2})=\frac{196}{\pi}$

Find the LCD of the following list of fractions. --14/10, -12/b

muminat

If I read your post properly, the two fractions are -14/10 and -12/b.

The LCD is found by finding prime factors of each term, then collecting the ones that appear the most.

10 = 2 x 5
b = b

2 x 5 x b = 10b
