Exercice d'application 1
Question
Factorise chacune des expressions suivantes :
\(I= 8t + 8d +at + ad\)
\(J= 11c + eh + 11h + ec\)
Solution
\(I= 8t + 8d +at + ad\)
\(I = 8(t+d) + a(t +d)\)
\(I = (t+d)(8+a)\)
\(J= 11c + eh + 11h + ec\)
\(J = 11c + 11h + eh + ec\)
\(J = 11 (c + h) + e(h +c)\)
\(J = (c + h)(11 + e )\)
