where a = 1 b= -2a c = (a+b)(a+b)
by simplification
x²-2ax + a² - b²
by putting value in formula
Frome here two cases are possible
1st case
2nd case
- here we apply quadratic formula to find value of x in given equation
- then as we can see we reduce equation further
- as we can see c = (a-b)(a+b) which = a² -b² property
- then we put value in equation and get two conditions
- solve both of them and get answer
- you could also solve this equation by factorising the mid term
