I need help I have to indicate how many terms it contains then copy and simplify each expression by combining like terms
1 answer:
Answer:
b) −3y2−2x+1
d) −4xy+4y2−y−10
Step-by-step explanation:
b) -4x <u>+ y2</u> <em>- 9</em> <em>+ 10</em> - x + 3x<u> - 4y2</u>
<u>(i have just underlined, italic and made it bold to show the like terms)</u>
-4x - x + 3x = -2x
y2 - 4y2 = -3y2
-9 + 10 = 1
-2x - 3y2 + 1
d) 0 - 20 <u>- 5xy</u> + 4y2 + 10 - y <u>+ xy</u>
<u>(i have just underlined, italic and made it bold to show the like terms, however the '-y' and '4y2' have no like terms)</u>
0 - 20 + 10 = - 10
-5xy + xy = - 4xy
-10-4xy+4y2-y
