practice questions on algebric equations for grade 8

Answer 1

Answer:

(a+b)square =a2+b2+2ab

Answer 2

Answer:

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

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

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

$( {a + b})^{3} = {a}^{3} + {b}^{3} + 3ab(a + b)$

$( {a - b})^{3} = {a}^{3} - {b}^{3} - 3ab(a - b)$

and many more
