Answer:
- 4x³ - 33x² + 31x - 3
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x²(- 4x + 3) + 9x(- 4x + 3) - 1 (- 4x + 3) ← distribute all 3 parenthesis
= - 4x³ + 3x² - 36x² + 27x + 4x - 3 ← collect like terms
= - 4x³ - 33x² + 31x - 3
One zero is - 1
because p(-1) = (-1)^3 + (-1)^2 -4(-1)- 4 = 0
So one factor of p(x) is x + 1
Dividing p(x) by x + 1 gives the quotient
x^2 - 4
x - 2)(x + 2) = 0
x = 2, -2
The zeroes are -2,-1 and 2
Answer:
To find the gradient it's the difference in the y values divided by the difference in the x values.

where
c
is the y intercept. But we know it goes through the origin (0,0)
#=> y=-2x+0
