Answer:
b = 10
-2d = -38
x = -1.2
Step-by-step explanation:
b = 10 and x = -1.2 only have one variable. You can divide -2 to both sides for -2d = -38 getting d = 19.
0.1 = 0.1 have no variable meaning that any number can be correct in the equation
1/3 ≠ 1/3 has a cross in the equal sign meaning that there is no correct answer for the equation.
Answer:
The roots of a quadratic equation simply tell what values of x will make the equation true. A quadratic function is a function where the largest power for the variable is 2. ... A quadratic equation is given to you so that you can solve it for the variable. A quadratic function is given to you so that you can graph it.
