if x-1 is a factor of P(x)=x^3- 5x^2 + 7x-3 which of the following represents the complete factorization for P(x)?​
kozerog [31]

Answer:

P(x) =  (x-1)² (x-3)

Step-by-step explanation:

P(x)=x³- 5x² + 7x-3 = x² (x-1) - 4x(x-1) + 3(x-1) = (x²-4x+3)(x-1)

P(x) = (x-1)(x-3)(x-1) = (x-1)² (x-3)

Tan A+ Tan (90-A) = secA .sec (90-A)​
sergeinik [125]

Answer:

see explanation

Step-by-step explanation:

Using the cofunction identities

tan(90 - A) = cotA and cscA = sec(90- A)

Consider the left side

tanA + tan(90 - A)

= tanA + cotA

= \frac{sinA}{cosA} + \frac{cosA}{sinA}

= \frac{sin^2A+cos^2A}{cosAsinA}

= \frac{1}{cosAsinA}

= \frac{1}{cosA} × \frac{1}{sinA}

= secA × cscA

= secA. sec(90 - A) = right side ⇒ verified
