The polynomial of degree 3 if we have zeros: -3, multiplicity 1; -4, multiplicity 2 is ![x^3+11x^2+40x+48](https://tex.z-dn.net/?f=x%5E3%2B11x%5E2%2B40x%2B48)
Step-by-step explanation:
We need to find the polynomial of degree 3 if we have zeros: -3, multiplicity 1; -4, multiplicity 2
Multiplicity tells how many times that zero occur:
s0 zeros are: -3,-4,-4
or we can write as: x=-3,x=-4 and x=-4
or x+3=0, x+4=0, x+4=0
Multiplying all terms to find the polynomial of degree 3:
![(x+3)(x+4)(x+4)\\=(x(x+4)+3(x+4))(x+4)\\=(x^2+4x+3x+12)(x+4)\\=(x^2+7x+12)(x+4)\\=x(x^2+7x+12)+4(x^2+7x+12)\\=x^3+7x^2+12x+4x^2+28x+48\\=x^3+7x^2+4x^2+12x+28x+48\\=x^3+11x^2+40x+48](https://tex.z-dn.net/?f=%28x%2B3%29%28x%2B4%29%28x%2B4%29%5C%5C%3D%28x%28x%2B4%29%2B3%28x%2B4%29%29%28x%2B4%29%5C%5C%3D%28x%5E2%2B4x%2B3x%2B12%29%28x%2B4%29%5C%5C%3D%28x%5E2%2B7x%2B12%29%28x%2B4%29%5C%5C%3Dx%28x%5E2%2B7x%2B12%29%2B4%28x%5E2%2B7x%2B12%29%5C%5C%3Dx%5E3%2B7x%5E2%2B12x%2B4x%5E2%2B28x%2B48%5C%5C%3Dx%5E3%2B7x%5E2%2B4x%5E2%2B12x%2B28x%2B48%5C%5C%3Dx%5E3%2B11x%5E2%2B40x%2B48)
So, the polynomial of degree 3 if we have zeros: -3, multiplicity 1; -4, multiplicity 2 is ![x^3+11x^2+40x+48](https://tex.z-dn.net/?f=x%5E3%2B11x%5E2%2B40x%2B48)
