Exercice 1 :
A= 25/35×(25/15-47/15)
= 25/35*(-22/15)
= -550/525
= -22/21
B= (5/9+1/9×5/2)²
= (5/9+5/18)²
= (10/18+5/18)²
= (15/18)²
= 25/36
Exercice 2 :
1) C= (3x-2)(2x+7)-(--3x-9)(2-3x)
= 6x²+21x-4x-14-(-6x+9x²-18+27x)
= 6x²+21x-4x-14+6x-9x²+18-27x
= -3x²-4x+4
2) Pour x= -3, C= -3×(-3)²-4×(-3)+4
= -3×9+12+4
= -27+16
= -11
