Bonjour!
1) Programme a = (2²+35)×2²+24
programme a = (4+35)×4+24
programme a = 39×4+24
programme a = 156+24
programme a = 180
Programme B = (2²+5)×10×2
programme b = (4+5)×20×2
programme b = 9×10×2
programme b = 180
2) programme a = (x²+35)×x²+24
programme b = (x²+5)×10×x
3) programme a = (x²+35)×x²+24
programme a = 2x⁴+35x²+24
programme b =(x²+5)×10×x
programme b = 10x²+50×x
