Question

find the value of the polynomial at the indicated values of variables p(y)=5y^2+4;y=-2/√5 ,4/√5
​

Answer 1

Answer:

p(-2/✓5), p(4✓5) = 8, 20

Step-by-step explanation:

p(y)=5y²+4

y=-2/✓5

p(-2/✓5)=5×[-2/✓5]²+4

=5×(4/5)+4

=4+4

=8

y=4/✓5

p(4/✓5)= 5×[4/✓5]²+4

=5×(16/5)+4

=16+4

=20
