Bonjour j’aurai besoin d’aide pour écrire la forme canonique de cette expression svp ! Je ne comprends pas la méthode. g(x)= 3x au carré + 5x -8

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

Use a calculator basically

If the diameter is 8 than the radius is 4 because 2r or 2*radius equals the diameter. 4*2=8. 8/2=4.
