Simplify the expression
10mn
15m

1) 10mn - 10×m×n

2)15m - 15×m

10×m×n×+15×m

=10mn+15m

factorize

common number(divisor) = 5

5m(2n+3)

5m*2n=10mn

5m*3=15m

Step-by-step explanation:

hello :

10mn /15m =2n /3  simplify by 5m

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
