Bonjour j'ai besoin d'aide slvp
1) Développez et réduire l'expression
A= (4x-7) (8x+9)
2) Factoriser les expressions
T= 25r-35+45t et P= 8g au carré+ 9g
3) Calculer la valeur numérique de l'expression
Y= 9m au carré - 5m+3 en substituant m par -2
merci a ceux qui m'aideront au plus vite <3

Salut !
1) (4x + 7)(8x + 9)
= 4x*8x + 4x*9 + 7*8x + 7*9
= 32x² + 36x + 56x + 63
= 32x² + 92x + 63
2) 25r - 35 + 45t = 5(5r - 7 + 9t)
8g² + 9g = g(8g + 9)
3) si x = -2
Y = 9(-2)² - 5(-2) + 3
= 36 + 10 + 3
= 49

1) A=(4x-7)(8x+9)
=(4x)×(8x)+(4x)×9-7×(8x)-7×9
=32x²+36x-56x-63
=32x²-20x-63
2) T=25r-35+45t
=5×5r-5×7+5×9t
=5(5r-7+9t)
P=8g²+9g
=g(8g+9)
desole
3) Y=9m²-5m+3
pour m=-2
Y=9×(-2)²-5×(-2)+3
=9×4+10+3
=36+10+3
=49
