Describe two ways to find the distance between two points in a coordinate plane?

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers
