Quadratic formula to find the values of x that are solutions to the equation 2x2 + 3x + 1 = 0

x = -0.5 or -1

Step-by-step explanation:

Given the quadratic equation;

2x² + 3x + 1 = 0

The standard form of a quadratic equation is ax² + bx + c = 0

Therefore, a = 2, b = 3 and c = 1

Quadratic equation formula is;

Substituting into the equation, we have;

Simplifying further, we have;

To find the value of x2;

Therefore, the value of x = -0.5 or -1

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
