Add 2 to each side.
m = 20/9 or 2 and 2/9
18m^2 - 12m + 2 = 2(9m^2 - 6m + 1) you can apply the formula (a - b)^2 = (a^2 - 2ab + b^2) or if you don't remmember it, continue to work: = 2(9m^2 - 3m - 3m + 1) = 2[(9m^2 - 3m) - (3m - 1)] = 2[3m(3m - 1) - (3m - 1)] = 2[(3m - 1)(3m - 1)] = 2(3m - 1)^2
factor it (m + 1)(9m + 2) m= -1 and -2/9
It is equivalent to 6-27m after expanding the brackets
m=1 How? -2=9m-11 -2+11=9 9=9m 9/9=9m/9 m=1
This may get complicated. Try and stay with us if you possibly can:11 - 9m = 2Subtract 11 from each side:- 9m = -9Divide each side by -9:m = 1
9m - 14 = 8 9m = -8 + 14 9m = 6 m = 6/9 = 2/3 or 0.667
9m = 6 m = 2/3
m = 2/3
M=2/3
Is the height 9m or 8m? Area of triangle = Base x Height / 2 If the height is 9m... The area is 37m squared If the height is 8m... The area is 24m squared.
Add 2 to each side.

3m^2 - 9m = 0 factor out 3m 3m(m - 3) = 0 m = 0 -------- or m = 3 --------
