Question

solve x²-2bx+(b²-a²)=0​

Answer 1

Answer:

x = b - a or b + a

Step-by-step explanation:

x² - 2bx + (b² - a²) = 0

-2b = -(b - a) * -(b + a)

b² - a² = -(b - a) * -(b + a)

=> x² - (b - a)x - (b + a)x + (b² - a²)

=> x(x - (b - a)) -(b + a) (x - (b - a))

=> (x -(b - a)) (x -(b + a))

=> x = b - a or b + a
