Question

Q3. Solve x square - 25x + 156= 0 completing the square.​

Answer 1

Step-by-step explanation:

by splitting the middle term we get

x square-(13+12)x+156=0

x square-13x-12x+156=0

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

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

from here.....

x=13 or x=12

Answer 2

Answer:

Step-by-step explanation:

x2 -12x-13x+156=0

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

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

X=13or 12
