Which shows the correct substitution of the values a, b, and c from the equation 1 = -2x + 3x² + 1 into the quadratic
formula?
Quadratic formula: x =
-b± √b²-4ac
2a
Ox==(-2) ± √(-2)² – 4(3)(0)
2(3)
0 x==(-2) ± √(-2)² - 4(3)(2)
X=
0 x==(-
-(-2) ± √(-2)²-4(3)(1)
2 (3)
-3±√√3²-4(-2)(0)
2(-2)
The coefficient 'a' for the quadratic term is a = 3 The coefficient 'b' for the linear term is b = -2 The coefficient 'c' is 0 Step-by-step explanation : The given expression is,
To solve this problem we are using quadratic formula. The general quadratic equation is,
Formula used :
Now we a have to solve the above equation and we get the value of 'x'.
a = 3, b = -2, c = 0
The coefficient 'a' for the quadratic term is a = 3 The coefficient 'b' for the linear term is b = -2 The coefficient 'c' is 0
