Answer:
5
Step-by-step explanation:
a polynomial has one quadratic factor and 3 linear factors. One of the linear factors has multiplicity two. What is the degree of the polynomial
A polynomial with one quadratic obtains the forms ( ax² +bx +c ) with 3 linear factors.
Suppose the three linear fractions are :
(x- P) (x-Q) (x- R)
∴
The polynomial = ( ax² +bx +c )(x- P) (x-Q) (x- R)
By factorization, the highest degree of the polynomial = 5
5.66 (3 significant figures)

Answer:
<h2><u><em>
x = 85</em></u></h2>
Step-by-step explanation:
20% of a number is 17 . find the number
divide 17 by 20 and you find 1%, multiply by 100 and you get 100%
x = 17 : 20 * 100
x = 0.85 * 100
x = <u><em>85</em></u>
Answer:
x² - 5x + 4
Step-by-step explanation:
note that (p - q)(x) = p(x) - q(x), thus
p(x) - q(x)
= x² - 1 - 5(x - 1) ← distribute parenthesis by - 5
= x² - 1 - 5x + 5 ← collect like terms
= x² - 5x + 4
