Algebraic Identities
Math ⇒ Algebra
Algebraic Identities starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Algebraic Identities.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

If a = 0 and b = 7, find the value of (a + b)2.
If a = 1 and b = -2, find the value of (a + b)3.
If a = 2 and b = 5, find the value of (a + b)2.
If a = 3 and b = 2, find the value of (a + b)(a - b).
If x = 2 and y = 1, calculate (x + y)(x - y).
If x = 3 and y = 4, calculate (x - y)2.
Which identity is used to expand (a + b)(a - b)?
Which identity is used to expand (a + b)3?
Given that (a + b)2 + (a - b)2 = 2(a2 + b2), prove this identity for all real numbers a and b.
Given that (a + b)3 + (a - b)3 = 2a3 + 6ab2, find the value of a and b if a = 2b.
If p = 3 and q = -2, calculate the value of (p + q)3 - (p - q)3.
