Answer:
it's = 0
you have to use the steps of maths
Answer:
24x^3+34x^2+53x+8
Step-by-step explanation:
P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
I believe it would be the first choice
Hope that helps!
