Bonsoir,
[tex]A=(x+2)(x+5)\\A=x^2+5x+2x+10\\A=x^2+7x+10[/tex]
[tex]B=(3x-7)(5x-2)\\B=15x^2-6x-35x+14\\B=15x^2-41x+14[/tex]
[tex]C=(x+3)(4-x)\\C=4x-x^2+12-3x\\C=-x^2+x+12[/tex]
bonsoir,
A= (x+2) (x+5)
= x² +5x +2x +10
= x² +7x +10
B= (3x-7) (5x-2)
= 15x² -6x -35x +14
= 15x² -41x +14
C= (x+3) (4-x)
= 4x -x² +12 -3x
= -x² +x +12
