Question

simplify this the answer is 75/16 with the value m= -1/2

Answer 1

For m=2

4(4-6-2)+5
4×(-4) +5
-16+5
-11
####

For m=-1/2

1/4(1/4+ 3/2- 2) +5
1/4( 1+6-8/4) +5
1/4 (-1/4)+5
-1/16+5
(-1+80)/16
79/16
#####

Answer 2

p(m)=m²(m²-3m-2)+5
m=2
p(2)= (2)²( (2)²-3*2-2)+5
=4(4-6-2)+5
= 4(0)+5
=0+5
= 5

p(-1/2)=(-1/2)²( (-1/2)²-3*(-1/2)-2)+5
=1/4(1/4+3/2-2)+5
=1/4(1+6-8/4)+5
=1/4(-1/4)+5
=-1/16+5
= -5+400/16
= 395/16
= 24.687
