Question

add 3x²-2y+10xy and 4x²+3y²-3xy​

Answer 1

Answer:

5x2 - 2x + 8

Step-by-step explanation:

Add 2x2 − 3x + 1 to the sum of 3x2 − 2x and 3x + 7.

ANSWER:

Sum of 3x2 - 2x and 3x + 7

= (3x2 - 2x) + ( 3x +7)

= 3x2 - 2x + 3x + 7

= (3x2 + x  + 7)

Now, required expression = (2x2 - 3x + 1) + (3x2 + x  + 7)

                                           = 2x2 + 3x2 - 3x + x + 1 + 7

                                           = 5x2 - 2x + 8
