Nice Explanation ❤

[@Steven-v6l]

"( )" are parentheses ... "(" open parenthesis, and ")" close parenthesis
"[ ]" are brackets ... "[" open bracket, and "]" close bracket
Also to avoid confusion when using quadratic formula:
use x and y NOT a and b. So use x^2 - y =13 and y^2 - x = 13

[@ganeshdas3174]

a = - 4 and b = 3 are satisfying values

[@cabasantbab]

A=-4
B=3

[@MiyanPunctureWaleVsBrahmanVaad]

3, -4

[@LeonardHarris]

can't use b to be two different variables at 3:46

[@mdshajjadhossain8450]

Would you suggest me some books for Algebra?

[@kajalbanerjee8220]

A=minus 4&b=3.

[@一-1-0]

A=-4 & b=3 *?
