Factorize. (i) 2mn +m^2-6n - 3m (ii) 4y^2 -81 (iii) t^2 - 6t+8

(i) (m-3)(2n+m) (ii) (2y+9)(2y-9) (iii) (t-4)(t-2)

Step-by-step explanation:

2mn+m^2-6n-3m

m(2n+m)-3(2n+m)

(m-3)(2n+m)

(m-3)(2n+m)

4y^2-81

(2y+9)(2y-9)

(2y+9)(2y-9)

t^2-6t+8

(t-4)(t-2)

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

factor trees are nice.
