Question

A(x) = 7x3 − 3x2 − x + 10
A(2) =

Answer 1

Tú cuentas valor para x=2:
$A(2)=7 \cdot 2^{3} - 3 \cdot 2^{2} - 2 +10=7 \cdot 8-3 \cdot 4-2+10=56-12-2+10 \\ A(2)=52$

Answer 2

A(x) = 7x³ -3x² -x +10
resolver A(2)

solucion
A(x) = 7x³ - 3x² -x +10
A(2) = 7*2³ - 3*2² -2+10
A(2) = 7*8 -3*4+8
A(2) = 56 -12 +8
A(2) = 64-12
A(2) =52
