Answer:

Step-by-step explanation:

For each expression, <u>we need to factor out the GCF(Greatest common factor)</u>

a) $x^2+2x$

Here, the GCF is $x$ . So, we will get.....

$x^2+2x\\ \\ =x(\frac{x^2}{x}+ \frac{2x}{x}) \\ \\ =x(x+2)$

b) $2x^2-6x$

Here, the GCF is $2x$ . So, we will get......

$2x^2-6x\\ \\ =2x(\frac{2x^2}{2x}- \frac{6x}{2x}) \\ \\ =2x(x-3)$

c) $15x-10x^3$

Here, the GCF is $5x$ . So, we will get.......

$15x-10x^3\\ \\ =5x(\frac{15x}{5x}- \frac{10x^3}{5x}) \\ \\ =5x(3-2x^2)$

d) $9x^2+3x^3$

Here, the GCF is $3x^2$ . So, we will get.......

$9x^2+3x^3\\ \\ =3x^2(\frac{9x^2}{3x^2}+ \frac{3x^3}{3x^2}) \\ \\ =3x^2(3+x)$

Find the center and radius of the circle x^2+y^2=49

Alex_Xolod [135]

The circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r".
Therefore the radius is √49=7 and the center coordinates are (0,0)
