m^2 - 4m = 140

m^2 - 4m - 140 = 0

(m - 14)(m + 10) = 0

m - 14 = 0 , m + 10 = 0

m = 14, m = - 10 <----discard m = - 10 since it is negative

solving its angle frome m^2 - 4m

m^2 - 4m = 14^2 - 4(14) = 140° answer//

solving the length of the parallelogram

x^2 + 4x = 5

x^2 + 4x - 5 = 0

(x + 5)(x - 1) = 0

x + 5 = 0 , x - 1 = 0

x = - 5 discard - 5, x = 1

x^2 + 4x = (1)^2 + 4(1) = 5 answer//

(m^2 - 4m)° = 140°

m = 14, -10

x^2 + 4x = 5

x(x + 4) = 5

x = 1, -5
