Question

pls tell me... maths formulas upto 10 standard​

Answer 1

Answer:

Step-by-step explanation:

(A+b)*2=a*2+2ab+b*2

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

When u have a unique solution he formula used to find the equations is a1/a2 is not equal to b1/b2 .

When no solution : a1/a2=b1/b2 is not equal to c1/c2.

When it is infinitely many solutions : a1/a2=b1/b2=c1/c2 .

I think this helps u
