How to solve the Quadratic formul​

Mathematics
1 answer:
Marat540 [252]3 years ago
7 0

Answer:

The answer is x=-6, x=8

Step-by-step explanation:

I recommend using the quadratic formula to solve this problem.

x^2=a

-2x=b

-48=c

Plug it into the quadratic formula.

New equation:\frac{2+-\sqrt{(-2)^2-4(1)(-48)}}{2(1)}

Simplify

Equation: \frac{2+-\sqrt{4+192}}{2}

Add 4 and 192.

Equation: \frac{2+-\sqrt{196}}{2}

Do the square root of 196.

Equation: \frac{2+-14}{2}

Make into two different equations.

Equation 1: \frac{2+14}{2}

Equation 2: \frac{2-14}{2}

Solve the two equations and you will get -6 and 8.  Hope this helps!

I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.
