Answer:
2b²(8b²+15b-6)
Step-by-step explanation:
16+30b³-12b²
2b²(8b²+15b-6)
This is not further factorable. If you want to find the roots, you'd have to use the quadratic formula for the polynomial in the parentheses. Therefore that is our final answer.
Answer:

Step-by-step explanation:
(3)
Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 5 ⇒ m =
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
= -
y = x + 4 ⇒ m =
y = - x + 5 ⇒ m = -
y = x + 3 ⇒ m =
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
= -
the 2nd and 4th lines are perpendicular
