Question

3) 10m3n2 - 15m2n + 25m

4) x2 + 12x + 36

Answer 1

4) (x + 6)(x + 6)

Answer 2

3)10m3n2 - 15m2n + 25m

   5m(2m^2n^2 - 3mn + 5)

4) x2 + 12x + 36

(x +6) (x+6)

or

(x+6)^2

Answer 3

3. 5m(2m^2n^2 - 3mn + 5)

4.  (x+6)^2

Answer 4

3) 10m3n2 - 15m2n + 25m

Get the common:

5m (2m^2n^2 - 3mn +5)

4) x2 + 12x + 36

x^2 = x * x

36 = 6 * 6

(x+6) (x+6) -----> ans

Answer 5

10m^3n^2 - 15m^2n + 25m

5m(2m^2n^2 - 3mn + 5) {common factor}

In the trinomial, ac = 2(5) = +10 and no factors of +10  add to -3

Trinomial is prime

x^2 + 12x + 36

Factors of +36 that add to +12 are +6 & +6

(x + 6)(x + 6)
