Question

all 12 alzebric identites

Answer 1

Hey Mate here is your answer.....
.
1. (a+b)2 = a2 + 2ab + b2


2. (a-b)2 = a2 - 2ab + b2


3. (a+b) (a-b) = a2 -b2


4. (x + a)(x + b) = x2 + (a + b) x + ab


5. (x + a)(x - b) = x2 + (a - b) x - ab


6. (x - a)(x + b) = x2 + (b - a) x - ab


7. (x - a)(x - b) = x2 - (a + b)x + ab


8. (a + b)3 = a3 + b3 +3ab (a + b)


9. (a - b)3 = a3 - b3 - 3ab (a - b)


10. (x + y + z)2 = x2 + y2 + z2 + 2xy +2yz + 2xz


11. (x + y - z)2 = x2 + y2 + z2 + 2xy - 2yz - 2xz


12. (x - y + z)2 = x2 + y2 + z2 - 2xy - 2yz + 2xz


13. (x - y - z)2 = x2 + y2 + z2 - 2xy + 2yz - 2xz


14. x3 + y3 + z3 - 3xyz = (x + y + z) (x2 + y2 + z2 - xy - yz -xz)


15. x2 + y2 = 1212 [(x+y)2 + (x-y)2]


16. (x+a) (x+b) (x+c) = x3+ (a + b + c ) x2 + (ab + bc +ca) x + abc


17.  x3 + y3 = (x + y) ( x2 - xy + y2)


18.  x3 - y3 = (x - y) ( x2 + xy + y2)


19.  x2 + y2 + z2 -xy -yz -zx = 1212 [(x-y)2 + (y -z)2 + (z -x)2]

Answer 2

Answer:

identities are:

Step-by-step explanation:

1.(a+b)*2=a*2+2ab+b*2

2.(a-b)*2=a*2-2ab+b*2

3.(a+b) (a-b)=a*2-b*2

4.(x+a) (x+b)=x*2+(a+b)x+ab
