Set y to 0 and solve. 0 = 4( -1/2 ) + 2.
x = -1/2
Answer:
never actually. We don't use things like these in real life but instead learn the problem solving and use that experience
Answer:
18 is the answer
Step-by-step explanation: Solve by multiplication/division first and then addition and/subtraction
Given the equation:
(1)

We need to find a, b and c. So, we know that a quadratic equation is given by:
(2)

Then, we need to order the equation (1) and to adjust it to the equation (2), so:

So, if we compare these two equations, the conclusion is:



(3)

Substituiting a, b and c into (3):

Finally, the results are two values:
