Factoriser chaque expression merci d’avance B=4t2+20x C=-5x2+25x D=-10-16a

Bonsoir,

Factoriser chaque expression:

B=4t²+20x

B= 4(t²+5x)

C=-5x²+25x

C= -5x(x-5)

D=-10-16a

D= 2(-5-8a)

Bonsoir,

Factoriser chaque expression :

B=4t²+20x

B = 4 (t² + 5x)

C=-5x²+25x

C= - 5x (x - 5)

D= -10-16a

D = 2 (- 5 - 8a)
