Solve x^2 - x = 2 using the quadratic formula. Show your work.

lesya [120]

The quadratic formula is the result of completing the square for ax^2+bx+c=0 when a,b, and c are unknown values. This result is:

x=(-b±√(b^2-4ac))/(2a), we have x^2-x-2=0 so

x=(1±√(1+8))/2

x=(1±√9)/2

x=(1±3)/2

x=-1 and 2

Yuri [45]

Answer:

As per the statement:

Mr. Roseanne will buy $12\frac{1}{2}$ pounds beef for for a cookout.

⇒ Weight of the beef he buy = $\frac{25}{2}$ pounds.

It is given that:

The price for the first 3 pounds of beef is $4.99 per pound.

then;

the price for 3 pounds he will pay= $3 \times 4.99 =\$ 14.97$

After that, the price is $4.49 per pound.

Remaining weight of beef left = $\frac{25}{2} -3 = \frac{19}{2}$ pounds.

then;

the price of $\frac{19}{2}$ pounds he will pay = $\frac{19}{2} \times 4.49= \$42.655$

now, total money he will pay for the $12\frac{1}{2}$ pounds beef = $14.97+42.655 = \$57.625$

Therefore, $57.625 will Mr. Roseanne pay for the beef
