MAFS.912.A-APR. 1.1
Kiera claimed that the sum of two linear polynomials with rational coefficients is
always a linear polynomial with rational coefficients.
Drag the six statements into a logical sequence to outline an argument that proves
this claim.
P(x) + f(x) = (ax+cx) + (b+d)
P(x) + g(x) = (ax+b) + (cx+d)
Given p(x) = ax+b and g(x) = cx+d where a, b, c,
and d are rational numbers.
(a+c) and (b+d) are rational numbers
So p(x) + g(x) is a linear polynomial with rational
coefficients.
P(x) + g(x) = (a+c)x + (b+d)
