Answer:
-35, 1493
Step-by-step explanation:
p(x) = 2x⁴ + 3x³ - 9x² + 16x + 13
p(-3) = 2(-3⁴) + 3(-3³) - 9(-3²) + 16(-3) + 13
-3² = 9
-3³ = -27
-3⁴ = 81
p(-3) = 2(81) + 3(-27) -9(9) - 48 + 13
p(-3) = 162 - 81 - 81 -48 + 13
81 + 81 = 162 therefore 162 - 81 - 81 cancels
-48 + 13 = -35
p(5) = 2(5⁴) + 3(5³) - 9(5²) + 16(5) + 13
5² = 25
5³ = 125
5⁴ = 625
p(5) = 2(625) + 3(125) - 9(25) + 80 + 13
p(5) = 1250 + 375 - 225 + 93
p(5) = 1250 + 150 + 93
p(5) = 1493
