Question

1) x²-4=0
2) y²-5y+6=0​

Answer 1

Answer:

1).Step 1:- x^2-4=0

Step 2:- x^2=4

Step 3:- x=√4

Step 4:- x=2

Step-by-step explanation:

2). Step 1:- y^2-5y+6=0

Step 2:- y^2-3y-2y+6=0

Step 3:- y(y-3)-2(y-3)=0

Step 4:- (y-2) & (y-3)

Step 5:- y-2=0 | y-3=0

Step 6:- y=2 | y=3

Answer 2

Answer:

1)x2+4=0

x2=0+4

x2=4

x=√4

x=2

Step-by-step explanation:

y2-5y+6=0

y2-3y-2y+6=0

(y2-3y) (-2y+6)=0

y(y-3) -2(y-3)=0

(y-3) (y-2) =0

y = 2or3
