Bonjour,
Simplifier et réduire les expressions littérales:
π+2*π+3*π =6π
b-b = 0
1*b+(-1)*b= b-b= 0
x*x*x+x*x+x²= x³+x²+x²= x³+2x²
(-a)+(-3a)+(-5a)= -a-3a-5a= -9a
(-a)-(-3a)-(-5a)= -a+3a+5a= 7a
r-r*r+2*r*4*r= r-r²+8r²= 7r²+r
(-2)*h+(-2)*h= -2h-2h= -4h
Bonjour
π+2*π+3*π = 6π
b - b = 0
b - b = 0
x* x *x + x*x + x²= x³ + x²+ x²= x³+2 x²
(-a)+(-3 a)+(-5 a)= - a- 3 a-5 a= -9 a
(-a)-(-3 a)-(- 5 a)= -a +3 a+ 5 a= 7 a
r-r*r+2*r*4*r= r-r²+8 r²= 7 r²+ r
(-2)*h+(-2)*h= -2 h -2 h= - 4 h
