Question

x square - 25 x + 156 equal to zero​

Answer 1

Answer:

x2-25x+156=0

x2-13x-12x+156=0

x(x-13)-12(x-13)=0

(x-12)(x-13)=0

x-12=0

x=12

x-13=0

x=13

Answer 2

Answer:

x^2-25x+156=0

=> x^2-13x-12x+156=0

=> x(x-13)-12(x-13)=0

=> (x-12)(x-13)=0

Either,

x-12=0 or x-13=0

=> x=12 => x=13
