12.	X2 - (a + b)x + ab = 0 factorise
Answer» Answer: x2 - (a + B) X + ab = 0 ⇒ x2 - ax - BX + ab = 0 ⇒ x (x -a) -b(x -a) = 0 ⇒ (x -a) (x -b) = 0 since x -a = 0 or x -b = 0 then x = a or x = b

12.

X2 - (a + b)x + ab = 0 factorise

Answer»

Answer:

x2 - (a + B) X + ab = 0

⇒ x2 - ax - BX + ab = 0

⇒ x (x -a) -b(x -a) = 0

⇒ (x -a) (x -b) = 0

since x -a = 0 or x -b = 0

then x = a or x = b

On differentiating both sides w.r.t. t RESPECTIVELY, we get

dx/dt = cos t and dy/dt = sec² t

Therefore, dy/dt/dx/dt = sec² t/cos t = 1/cos³t

hope it will help you get
