The value of x is x=2.57338 and x=−0.906718
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
3x²-5x-7=0
Using the discriminant method,
a = 3, b = -5, and c = -7
x= -b± √b²-4ac / 2a
x= 5 ± √25 + 84/ 6
x= 5± √ 109
Hence, x=2.57338 and x=−0.906718

It would take about 25 months for the cost of leasing a billboard be the same for both companies.
<h3>
Linear function</h3>
A linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.
