Question

ayudenme porfa conestos ejercicios de binomio al cuadrado: (a + 6)2 ..... (5m+3)2......(2x+1)2.......(m7-1)2.....(6x5-4)2
gracias :) :)

Answer 1

La formula general es (a+b)2 = a2 + 2ab + b2
(a-b)2 = a2 - 2ab + b2

Answer 2

(a+6)(a+6) = a2+36
(5m+3)(5m+3) = 25m2+9
(2x+1)(2x+1) = 4x2+1
(m-7-1)(m-7-1) = m2 - 49 -1
(6x5-4)(6x5-4) = 36x - 1
