Hey, here is your answer...

Given, (5x - 2y) = 7 and xy = 2, need to find the value of [(5x +2y)^2]

We know that,

${(a - b)}^{2} + 4ab \: = \: {(a \: + \: b) }^{2} \\ {(5x - 2y)}^{2} + 4xy = {(5x + 2y)}^{2} \\ {</em><em>(</em><em>7</em><em>)</em><em> </em><em>}^{2} + 4(2) = {(5x + 2y)}^{2} \\ 49 + 8 = {(5x + 2y) }^{2} \\ {(5x + 2y)}^{2} = 57 </em><em> \\ \\ \\ hope \: this \: helps \: you... \\ thank \: you.. \\ plzz \: mark \: me \: as \: brainliest..$
