Question

p(t)= (t-5)(t-4), Then coefficient of t i
s​

Answer 1

Answer:

$p(t) = (t - 5)(t - 4)$

$(t - 5)(t - 4)$

$t(t - 4) - 5(t - 4)$

${t}^{2} - 4t - 5t - 4$

${t}^{2} - 9t - 4$

Coefficient of t is -9

Ans. -9

Hope it helps.

Answer 2

$p(t) = (t - 5)(t - 4)$

$= t(t - 4) - 5(t - 4)$

$= {t}^{2} - 4t - 5t + 20$

$= {t}^{2} - 9t + 20$

Coefficient is 9
