change the quadratic equation into standard form

Question

Change into standard form x^2+4x=-6

 

Answer 1

Standerd form of quadratic equation is ax^2+bx+c = 0

here x is variable,a is not equal to 0.

x^2+4x = -6

Add 6 to each side.

x^2+4x+6 = -6+6

x^2+4x+6 = 0

a = 1,b = 4, c = 6.

Standerd form of equation is x^2+4x+6 = 0
