bonjour!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A  = x² + 5 x + 10

a = 0  ⇔ A =  10

a = - 2 ⇔ A = 4 - 10 + 10 = 4

a = 10 ⇔ A = 100 + 50 + 10 = 160

a = √2 ⇔ A = 2 + 5 √2 + 10 = 12 + 5 √2

INEQUATION

Bonjour,

A = x² + 5x+10.

Calculer pour x:

A(0) = 0² + 5(0)+10= 10

A(-2) = (-2)² + 5(-2)+10= 4-10+10= 4

A(10) = (10)² + 5(10)+10= 100+50+10= 160

A(√2) = (√2)² + 5(√2)+10= 2+10+5√2= 12+5√2
