Question

p(x) = 5- 4x+2x^2 find p(0),p(3),p(-2)​

Answer 1

SOLUTION

p(x)= 5-4x+ 2x^2

Find =) p(0) , p(3), p(-2)

so,

2x^2-4x+5

=) p(0)= 2(0)^2- 4(0)+5

=) 0-0+5

=) p(0)= 5

_______________________________

p(3)= 2x^2 -4x +5

=) p(3)= 2(3)^2 -4(3)+5

=) 2× 9- 12+5

=) 18- 17

=) 1

p(3)= 1

__________________________________

p(-2)= 2(-2)^2 -4(-2)+ 5

=) p(-2)= 2(4)+ 8+5

=) p(-2)= 8+8+5

=) p(-2)= 21

hope it helps☺️⬆️
