Question

9x2-27x+14=0 factorise

Answer 1

9x^2-27x+14=0

9x^2 -21x-6x+14

3x(3x-7)-2(3x-7)

(3x-2)(3x-7) is ur ans

Answer 2

$9 {x}^{2} - 27x + 14 = 0 \\ 9 {x}^{2} - 21x - 6x + 14 = 0 \\ 3x(3x - 7) - 2(3x - 7) = 0 \\ (3x - 2)(3x - 7) = 0 \\ (3x - 2) = 0 \: or(3x - 7) = 0 \\ x = 2 \div 3 \: or \: x = 7 \div 3$
