The polynomial is not factorable, so use the quadratic formula.

y^2 + 8y + 19 = 0

x = (-b +- sqrt(b^2 - 4ac))/(2a)

x = (-8 +- sqrt(8^2 - 4(1)(19))/(2 * 1)

x = (-8 +- sqrt(64 - 76))/2

x = (-8 +- sqrt(-12))/2

If you have not learned imaginary/complex numbers, then the answer is "No solution" since there is no real number solution.

If you have learned imaginary/complex numbers, then we'll continue.

x = (-8 +- 2i sqrt(3))/2

x = -4 +- i sqrt(3)

Darren wins a coupon for $4 off the lunch special for each of five days he pays $75 for his 5 lunch specials write and solve an
Valentin [98]

The original price for one lunch special is $19.

<em><u>Explanation</u></em>

The original price for one lunch special is  'p'  dollar.

He wins a coupon for $4 off for each of five days. That means , <u>he needs to pay (p-4) dollar each day</u>.

So, the total amount needed to pay for 5 days = 5(p-4) dollar

Given that, <u>he pays $75 for his 5 lunch specials</u>. So the equation will be.....

5(p-4)= 75\\ \\ 5p-20=75\\ \\ 5p= 75+20\\ \\ 5p= 95\\ \\ p=\frac{95}{5}=19

So, the original price for one lunch special is $19.
