Write P(x) = x3 + x2 − 17x + 15 as a product of two factors, using x − 3 as one factor.

(x-1)(x-3)(x+5)

Step-by-step explanation:

Use the rational root theorem

Constant term = 15, Coefficient of leading term = 1

Factors of 15: 1, 3 , 5, 15

Factors of 1: 1

Therefore, (x-1) is a factor

Cubic equations must have 3 factors to get to the third degree, therefore (x-1)(x-3)(x+5)

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
