Question

What must be subtracted from 6z² - 2zy + 6y² to make it -4z² - 2zy - y²?​

Answer 1

$what \: must \: be \: subtracted \: to \: get$

$- 4 {z}^{2} - 2zy - y {}^{2} \: from \: 6 {z}^{2} - 2zy + 6y {}^{2}$

$(6 {z}^{2} - 2zy + 6y {}^{2} ) - ( - 4 {z}^{2} - 2zy - y {}^{2} )$

$(6 {z}^{2} - 4 {z}^{2} )( - 2zy - 2zy)(6 {y}^{2} - {y}^{2} )$

$(2)(6)$

$(2 - 6)is \: answer$
