Solve 8m² + 20m = 12 for m by factoring


Please show all work

Answers

Answer 1
Answer: 8m^(2)+20m=12 / :2
4m^(2)+10m=6
4m^(2)+10m-6 =0
\Delta=b^(2)-4ac
\Delta=100-(4*4*-6)
\Delta=100+96=196
x1=(-b-√(\Delta))/(8)
x1=(-10-14)/(8)
x1=(-24)/(8)
x1=-3
x1=(-b+√(\Delta))/(8)
x2=(-10+14)/(8)
x2=(1)/(2)

so you can write 8m^(2)+20m=12 / :2 as

8(m+3)(m-(1)/(2))=8*[m^(2)+2.5m-1.5]=0

What is the perimeter of the triangle expressed as a polynomial? Length: 8x-2
Length: 5x-4
Width: 9x-3
If you could show me how you got the complete answer I would really appreciate it.

Answers

The perimeter is the sum of the lengths of the three sides of the triangle. If "width" is the length of the 3rd side, then the perimeter is
  P = (8x-2) + (5x-4) + (9x-3)
  P = 8x + 5x + 9x -2 -4 -3
  P = (8+5+9)x -(2+4+3)
  P = 22x - 9
