Question

10. Subtract a2 - 2ax + x 2 from the sum of 3a2-5ax - x2 and -2 a2 +3 ax + 4x2
​

Answer 1

Answer:

= 2x2

Step-by-step explanation:

First we sum 3a2-5ax - x2 and -2 a2 +3 ax + 4x2

= 3a2-5ax-x2+(-2a2+3ax+4x2)

= 3a2-5ax-x2-2a2+3ax+4x2

= 3a2-2a2-5ax+3ax-x2+4x2

= a2-2ax+3x2

Now we subtract a2 - 2ax + x 2 from a2-2ax+3x2

= a2-2ax+3x2-(a2-2ax+x2)

= a2-2ax+3x2-a2+2ax-x2

= a2-a2-2ax+2ax+3x2-x2

= 2x2
