Answer:
Missing term = r²
Step-by-step explanation:
Given:
6r⁴ + 4r + …. -2r⁴ + 3r = 4r⁴ + r² +7r
Find:
Missing term
Computation:
Assume missing term = A
So,
6r⁴ + 4r + …. -2r⁴ + 3r = 4r⁴ + r² + 7r
6r⁴ + 4r + A -2r⁴ + 3r = 4r⁴ + r² + 7r
4r⁴ + 4r + A + 3r = 4r⁴ + r² + 7r
4r⁴ + 7r + A = 4r⁴ + r² +7r
A = r²
Missing term = r²
