Ill give brainliest Find the factors of these trinomials

Step-by-step explanation:

Use formula:

(a + b)^2 = a^2 + 2ab + b^2

Q12

16x^4 - 16x^2 + 4 =(4x^2)^2 - 2*4x^2*2 + 2^2 =(4x^2 - 2)^2 = 4(2x^2 - 1)^2

Q13

81p^6 + 90p^3 + 25 = (9p^3)^2 + 2*9p^3*5 + 5^2 = (9p^3 + 5)^2

Q14

4x^2 - 60x + 225 =(2x)^2 - 2*2x*15 + 15^2 =(2x^2 - 15)^2

Q15

25x^4 + 50x^2 + 25 = (5x^2)^2 + 2*5x^2*5 + 5^2 = (5x^2 + 5)^2 =25(x^2 + 1)^2

Q16

36y^2 - 156y + 169 = (6y)^2 - 2*6y*13 + 13^2 = (6y - 13)^2

Q17

144b^4 - 24b^2 + 1 =(12b^2)^2 - 2*12b^2*1 + 1^2 = (12b^2 - 1)^2

Q18

49q^8 + 28q^4 + 4 = (7q^4)^2 + 2*7q^4*2 + 2^2 = (7q^4 + 2)^2

32.10 is the correct answer
