Question

Write 4 standard identities for variables “a” and "b"

Answer 1

Answer:

ALGEBRAIC EXPRESSION IDENTITES

Step-by-step explanation:

$(a + b) ^{2} = a ^{2} + 2ab + b ^{2}$

$(a - b) ^{2} =a ^{2} - 2ab+b ^{2}$

$(a + b)(a - b) = a ^{2} - b ^{2}$

Answer 2

$(a+b) × (a-b) = a^2 - b^2$

$(a+b)^2 = a^2 + 2ab + b^2</p><p></p><p></p><p>$

$(a - b)^2 = a^2 - 2ab + b^2$
