Question

${4}^{2} + (4 \times 5) = {6}^{2}$
${5}^{2} + (4 \times 6) = {7}^{2}$
Explain using algebra​

Answer 1

Answer:

don't know the answer sorry

Answer 2

Answer:

In first case , i.e. 4² + ( 4 × 5 ) = 6²

let, x = 4

now, 5 =[ x+1 ]

ATQ,

LHS = x² + 4 ( x+1 )

=  x²+ 4x + 4

=  x² + 2 * 2 * x + 2²

=  ( x + 2 )² = ( 4 + 2 )² = 6² = RHS   ( proved )

Similarly it was also applied in second case
