Question

subtract 9x²y²z² from the sum 3x²y²z² and -7 x²y²z²​

Answer 1

Answer:

-13x²y²z²

Step-by-step explanation:

{(3x²y²z²)+(-7x²y²z²)} - {9x²y²z²}

= {-4x²y²z²}-{9x²y²z²}

= -13x²y²z²

Answer 2

Answer:

$-13 x^2y^2z^2$

Step-by-step explanation:

$3x^2y^2z^2 +(-7x^2y^2z^2)$

=> $3x^2y^2z^2 - 7x^2y^2z^2$

=> $-4x^2y^2z^2$

Next,

$-4x^2y^2z^2 - 9x^2y^2z^2$

=$-13x^2y^2z^2$
