Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. −5y^2 + 2y = −2

So before we can solve using the quadratic formula, we have to set the equation to zero. We can do that by adding 2 on both sides of the equation

Now we can use the quadratic formula, which is , with a=x^2 coefficient, b=x coefficient, and c=constant. We can form the equation as such:

Firstly, solve the exponents and the multiplications:

Next, do the addition within the radicals (these will be your exact solutions. but I'll solve for the decimal form as well.):

Next, solve for the rest on your calculator, and your answers will be (rounded to the thousandths) y = -0.463, 0.863

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
