Step-by-step explanation:
A quadratic function is a function of the form f(x) = ax^2 +bx+c, where a, b, and c are constants and a <> 0. (a not equal to 0)
The term ax^2
is called the quadratic term (hence the name given to the function), the term bx is called the linear term, and the term c is called the constant term.
Answer:
x² - 10x + 9 = (x-9)(x-1)
the factored expression would be (x-9)(x-1)
Answer:
see below
Step-by-step explanation:
2d+21 ≤11
Subtract 21
2d+21-21 ≤11 -21
2d ≤-10
Divide by 2
2d/2 ≤-10/2
d≤-5
