Question

find the sum of given polynomial p(y)=5ysq-9,q (y)=9ysq-4​

Answer 1

Step-by-step explanation:

$\sf \: p(y) = 5 {y}^{2} - 9 \\ \sf q(y) = 9 {y}^{2} - 4$

$\sf \: Sum = p(y) + q(y) \: \: \: \: \: \: \: \: \: \: \: \: \\ \sf = (5 {y}^{2} - 9) + (9 {y}^{2} - 4) \: \: \\ \sf \: = (5 {y}^{2} + 9 {y}^{2} ) + ( - 9 - 4) \\ \sf= (14 {y}^{2} - 13) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
