Apply binomial formula: Apply the square of a binomial formula, which is (a−b)2=a2−2ab+b2, to the expression (5x−y2)2.Calculation: (5x−y2)2=(5x)2−2⋅(5x)⋅(y2)+(y2)2
Calculate terms separately: Calculate each term separately.Calculation: (5x)2=25x2, −2⋅(5x)⋅(y2)=−10xy2, (y2)2=y4
Combine results: Combine the results from Step 2 to write the fully simplified form.Calculation: 25x2−10xy2+y4
