Question:-
Write the equation ( x + 2 )² = 2x + 5 in the form ax² + bx + c = 0, write the value of a ,b , c
Solution:-
Use this identity
=> ( a + b )² = a² + b² + 2ab , we get
=> ( x + 2 )² = 2x + 5
=> x² + 4 + 4x = 2x + 5
=> x² + 2x - 1 = 0
This equation is in the form of ax² + bx + c
The value of a = 1 , b = 2 and c = - 1
