Question

ax² + bx + c = 0 and equal to ax² + bx = - c What is the reason?​

Answer 1

Step-by-step explanation:

When solving an equation, we can bring the elements from left hand side to right hand by the changing the sign. For example, 4x+5y-6=0=>4x+5y=6.

2x/3=2=>2x=2×3

8x=64=>x=64/8

these are a few examples of sign changing. Multiplication turns into division and vice versa. Addition turns into subtraction and vice versa when brought to right hand side. You can also bring elements from right hand side to keft hand side by changing the sign For example,

5x=6=>5x/6=1 etc

Similarly in the quadratic equation that you asked, ax²+bx+c=0=>ax²+bx=-c(The sign of c changes when brought from left to right,i.e., from addition to subtraction)

Hope it helps! :)
