Question

Prove that (a+b)² = 4ab and verify using a =7 and b=3​

Answer 1

Step-by-step explanation:

a+b = 10

ab = 21

L. H. S ...(a+b)^2 = 100

R. H.S.. .... 4ab = 84

So.. L. H. S is Not Equal To R. H. S

Answer 2

Answer:

$\red {(a+b)^{2} = 4ab } \pink { ( False )}$

Step-by-step explanation:

$Given \: (a+b)^{2} = 4ab\: ---(1)$

$Substitute \: a = 7 \:and \:b=3\:in \: (1) ,we\:get$

$(7+3)^{2} = 4\times 7 \times 3$

$\implies 10^{2} = 81$

$\implies 100 = 81 \: \red { ( False )}$

Therefore.,

$\red {(a+b)^{2} = 4ab } \pink { ( False )}$
