write all the identities(of algebra)and make question of your own and solve it.
Pha:
Do you mean squaring identities or every identity because there are a lot of them
• (a + b)2 = a2 + 2ab + b2
• (a - b)2 = a2 - 2ab + b2
• (a + b)(a – b) = a2 – b2
• (x + a)(x + b) = x2 + (a + b) x + ab
these are the identities.pls help me
• (a - b)2 = a2 - 2ab + b2
• (a + b)(a – b) = a2 – b2
• (x + a)(x + b) = x2 + (a + b) x + ab
these are the identities.pls help me

• (a + b)2 = a2 + 2ab + b2
• (a - b)2 = a2 - 2ab + b2
• (a + b)(a – b) = a2 – b2
• (x + a)(x + b) = x2 + (a + b) x + ab
(3+4)2 = (3)2+2(3)(4)+(4)2
(3-4)2 = (3)2-2(3)(4)+(4)2
• (a - b)2 = a2 - 2ab + b2
• (a + b)(a – b) = a2 – b2
• (x + a)(x + b) = x2 + (a + b) x + ab
(3+4)2 = (3)2+2(3)(4)+(4)2
(3-4)2 = (3)2-2(3)(4)+(4)2
