A minus B Whole Square

Are you looking for a minus b ka whole square? You can check the formulas of a minus b ka whole square in three ways. We are going to share the (a-b)^2 algebra formulas for you as well as how to create (a-b)^2 and proof.

$$=> (a – b)^2 = (a – b)(a – b)$$
$$=> (a – b)(a – b) = a(a-b) – b(a-b)$$
$$=> a(a-b) – b(a-b) = a^2 – ab – ba + b^2$$
$$=> (a – b)^2 = a^2 – 2ab + b^2$$

(a-b)^2 Verifications

Check verification through a= 4 and b= 3.

put the value of a and b in LHS

$$(a-b)^2 = (4-3)^2$$

$$=>1^2 = 1$$

put the value of a and b in RHS

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

$$=> 4^2 – 2 \times 4 \times 3 + 3^2$$

$$=> 16 – 24 + 9 => 1$$

∴ $$LHS = RHS$$

Proof Formulas $$(a – b)^2 = a^2 – 2ab + b^2$$
