The polynomial p(x) has leading coefficient a and degree m, and the polynomial q(x) has leading coefficient b and degree n. Suppose the m>n, what is the leading coefficient and degree of px+q(x)?

a) Leading coefficient =a, degree=m

b) Leading coefficient =a, degree=m+n

c) Leading coefficient =a+b, degree=m

d) Leading coefficient =a+b, degree=m+n

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
