Answer:
5, -4, and -7
Step-by-step explanation:
5x² = 4x + 7
The standard form of a quadratic equation is
y = ax² + bx +c, where
a, b, and c are the coefficients.
If we convert your quadratic to the standard form, it becomes
5x² - 4x - 7 = 0
The coefficients are 5, -4, and -7.
Answer:
Laura = 14 Years
Juan = 21 years
Step-by-step explanation:
Let :
Laura's age = x
Juan's = x + 7
Product of their ages = (x) * (x + 7) = 294
x² + 7x = 294
x² + 7x - 294 = 0
x² + 21x - 14x - 294 = 0
x(x + 21) - 14(x + 21) = 0
(x + 21) = 0 or (x - 14) = 0
x = - 21 or x = 14
Age can't be negative
Hence, x = 14
Laura = 14 years
Juan = 14 + 7 = 21 = 21 years
