Question

a^2-b^2 geometrical proof of algebraic identities with image​

Answer 1

Answer:

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

Step-by-step explanation:

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

a^2-b^2=a^2-ab+ab-b^2

a^2-b^2=a^2-b^2{-ab and ab cancelled}

hence prooved

Answer 2

Step-by-step explanation:

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