GOOOD MORNING \

Step-by-step explanation:

Answer 2

${5x}^{2} + x - 1 \: is \: a \: quadratic \: polynomial \\ \\if \: the \: highest \: degree \: of \: the \: polynomial \: \\ is \: one \: it \: is \: said \: to \: be \: linear.... \\ general \: form \: of \: linear \: polynomial...... \\ ax + b = c \\ \\ if \: the \: highest \: degree \: of \: the \: polynomial \\ is \: two \: it \: is \: said \: to \: be \: quadratic... \\ general \: form \: of \: quadratic \: polynomial....... \\ a {x}^{2} + bx + c\\ \\ if \: the \: highest \: degree \: of \: the \: polynomial \\ is \: three \: it \: is \: said \: to \: be \: cubic.... \\ general \: form \: of \: cubic \: polynomial....... \\ a {x}^{3} + b {x}^{2} + cx + d \\ \\ similarly \\ i f\: the \: highest \: degree \: of \: the \: polynomial \: \\ is \: four \: it \: is \: said \: to \: be \: biquadratic \\ general \: form \: of \: biquadratic \: polynomial....... \\ a {x}^{4} + b {x}^{3} + c {x}^{2} + dx + e$
