Question

Find value of x (5x) (3x + 28)

Answer 1

ok so I got two different answers

5xtimes3x+28

5times3=15x

15x=28

28/15=1.866666667

x=1.867

or

5x+3x+28

5+3=8x

8x=28

8/28=3.5

x=3.5

Answer 2

0 or -9.33

Explanation:

We can find x by making the equation equal to 0:

`5\cdot{x}\cdot{(3\cdot{x}+28)}=0`

Therefore x can equal:

`5\cdot{x}=0`

`x=0`

or

`3\cdot{x}+28=0`

`x=-28/3=-9.33`
