Question

solve the sum with factorization method:x^4-5x^2y^2+4y^4(1st find middle term)​

Answer 1

${x}^{4} - {5x}^{2} {y}^{2} + {4y}^{4} \\ \\ {x}^{4} - 4 {x}^{2} {y}^{2} - {x}^{2} {y}^{2} + {4y}^{4} \\ \\ {x}^{2}( {x}^{2} - {4y}^{2}) - {y}^{2}( {x}^{2} - {4y}^{2})\\ \\( {x}^{2} - {4y}^{2})( {x}^{2} - {y}^{2} )$
