Question

1.Scoateti factorul comun: a.) 5x(x+2) + (x+2)la puterea a 2 in continuare minus 3(x+2)
b.) (x+1)(x+2)+4(x+1)la puterea a2 minus 4x(x+1)
c.)(x+2)(3x-7)-(x+2)(4x+2)+3(x+2)
d.)(2x-1)laputera a 2 minus (3x+2)(2x-1)+6x(2x-1)
e.)(5x-4)(3x-2) la puterea a doua minus (3x-2)la puterea 3+2(x+4)(3x-2) la puterea a doua .

Answer 1

a) (x-2)(5x+x-2-3)= (x-2)(6x-5)
b)(x-1)[x-2+4(x+1)-4x]=....
c) (x+2)(3x+7-4x-2+3)=...
d)(2x-1)(2x-1-3x-2+6x=...
