Group and factor
undistribute then undistribute again
remember
ab+ac=a(b+c)
this is important

6d^4+4d^3-6d^2-4d
undistribute 2d
2d(3d^3+2d^2-3d-2)
group insides
2d[(3d^3+2d^2)+(-3d-2)]
undistribute
2d[(d^2)(3d+2)+(-1)(3d+2)]
undistribute the (3d+2) part
(2d)(d^2-1)(3d+2)
factor that difference of 2 perfect squares
(2d)(d-1)(d+1)(3d+2)

77.
group
(45z^3+20z^2)+(9z+4)
factor
(5z^2)(9z+4)+(1)(9z+4)
undistribuet (9z+4)
(5z^2+1)(9z+4)

What is the ratio 175 to 250 written in fraction in LOWEST TERMS?

Lana71 [14]

For 175 : 250 divide them both by 25 to get $\frac{7}{10}$ < $\frac{175}{250}$
25 goes into 175 > 7 times > 25 into 250 is 10 times! > $\frac{7}{10}$
For the second one 16 : 40 just divide the top and bottom by 8 since 8 is a common factor of both which will give us $\frac{2}{5}$ .
8 goes into 16, 2 times and 40, 5 times.
