Question

Subtract : 5x 2 – 3x 2 + 8xy from 7x 2 + 3xy – 4x

Answer 1

Step-by-step explanation:

7x^2 - 4x + 3xy - ( 5x^2 - 3x^2 + 8xy)

= 7x^2 - 4x + 3xy - (2x^2 + 8xy)

= 7x^2 - 4x + 3xy - 2x^2 - 8xy

= 5x^2 - 4x - 5xy

Answer 2

Answer:

5x²-4x-5xy

Step-by-step explanation:

= ( 7x²-4x+3xy) -5x²-3x²+8xy

Split x² , xy, and x terms and solve.

• x² terms -

7x²-(5x²-3x²)

7x²-2x²

5x².

• Xy terms-

3xy-(8xy)

-5xy

• X term-

-4x

upon combining

we get

5x²-5xy-4x
