Question

write the formula of all chapter in class 10 maths.​

Answer 1

Step-by-step explanation:

(a+b)2 = a2 + b2 + 2ab.

(a-b)2 = a2 + b2 – 2ab.

(a+b) (a-b) = a2 – b. ...

(x + a)(x + b) = x2 + (a + b)x + ab.

(x + a)(x – b) = x2 + (a – b)x – ab.

(a + b)3 = a3 + b3 + 3ab(a + b)

(a – b)3 = a3 – b3 – 3ab(a – b)

(x – a)(x + b) = x2 + (b – a)x – ab.

Answer 2

✦✧✧ (ᴀ+ʙ)2 = ᴀ2 + ʙ2 + 2ᴀʙ.

(ᴀ-ʙ)2 = ᴀ2 + ʙ2 – 2ᴀʙ.

(ᴀ+ʙ) (ᴀ-ʙ) = ᴀ2 – ʙ. ...

(x + ᴀ)(x + ʙ) = x2 + (ᴀ + ʙ)x + ᴀʙ.

(x + ᴀ)(x – ʙ) = x2 + (ᴀ – ʙ)x – ᴀʙ.

(ᴀ + ʙ)3 = ᴀ3 + ʙ3 + 3ᴀʙ(ᴀ + ʙ)

(ᴀ – ʙ)3 = ᴀ3 – ʙ3 – 3ᴀʙ(ᴀ – ʙ)

(x – ᴀ)(x + ʙ) = x2 + (ʙ – ᴀ)x – ᴀʙ. ✧✧✦
