Question

answer this one ques 11 ex 5.2 pleaseeeeee​

Answer 1

Step-by-step explanation:

${4x}^{2} + {9y}^{2} - {25z}^{2} + 12xy \\ ( {2x}^{2} ) + ( {3y}^{2} ) - ( {5x}^{2} ) + 2.(2x)(3x) \\ (( {2x}^{2} ) + ( {3x}^{2} ) + 2(2x)(3y)) - ( {5z}^{2} ) \\ ( {2x + 3y)}^{2} - ( {5z}^{2}) \: \: \: \: \: \: \: \: \: (as \: we \: know \: {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab) \\ use \: now \: {{a}^{2} - {b}^{2} } = (a + b)(a - b) \\ now \\( 2x + 3y - 5z) \: \: \: (2x + 3y + 2z) \: \: \: \: \: are \: factore \: of \: given \: polynomial$

I will hope it's help you
