Answer:
Prime factors are factors of a number that are, themselves, prime numbers. There are many methods to find the prime factors of a number, but one of the most common is to use a prime factor tree.
Answer:
-6 ;
ax² + bx + c ;
-1
Step-by-step explanation:
1)
Give thequadratic equation :
4x² - 6x - 5
The values of a, b, c are the Coefficient of x², x and the constant respectively
Therefore, the value of b is the Coefficient of x = - 6
2.)
Standard form of a quadratic equation is :
ax² + bx + c
a = Coefficient of x² ; b = Coefficient of x ; c is a constant
3.)
2x² - 4x + 7
Axis of symmetry :
-b / 2a
a = 2 ; b = - 4, c = 7
-b / 2a = - 4 / 2(2)
= - 4 / 4
= - 1
The seventh grade completed more assignments than sixth and eighth grade did.
