Step-by-step explanation:
Answer:
-y^2
Step-by-step explanation:
x(x-2y)-(y-x)^2=
Distribute
x^2 -2xy -(y-x)^2=
Foil
x^2 -2xy -(y^2 -2xy+x^2)=
Distribute the minus sign
x^2 -2xy -y^2 +2xy-x^2=
Combine like terms
-y^2
Answer:
0
Step-by-step explanation:
Anything times 0 is 0
First you want to turn both fractions into improper fractions. So 1 4/7 would now be 11/7 because 1 x 7 + 4 is 11. And -1 4/8 will now be -12/8 because 1 x 8 + 4 is 12. Now you must find the common denominator. 8 x 7 is equal to 56 so the common denominator is 56. So now we are adding 11/56 + (-12/56). 11 plus 12 is 23. So we have 23/56. 23 can go into 56 two times because 23 x 2 = 46. There is 10 left over so our final answer is -2 10/56. In simplest form our answer would be -2 5/28
