If a/b and c/d are rational expressions then a/b x c/d = a/b x c/d
true or false

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

Which one ? is the answer and how to find this answer

X+ y = 5 ; x - y =3 solve using linear combination
