Question

punctele d, e,f va rooooggggg am nevoie acmm

Answer 1

Răspuns:

Explicație pas cu pas:

d)(3a-5)²+2(3a-5)+(a-5)(3a-5)=(3a-5)(3a-5+2+a-5)=(3a-5)(4a-8)=

=4(a-2)(3a-5)

e)(5-2x)(7x-2)-7x(7x-2)+(7x-2)²=(7x-2)(5-2x-7x+7x-2)=(7x-2)(3-2x)

f)(y-6)³+(y+1)(y-6)²-(5-3y)(y-6)²=(y-6)²(y-6+y+1-5+3y)=(y-6)²(5y+2)

Answer 2

Răspuns:

Explicație pas cu pas:

d)(3a-5)²+2(3a-5)+(a-5)(3a-5)=

(3a-5)(3a-5+2+a-5)=

(3a-5)(4a-8)==4(a-2)(3a-5)

e)(5-2x)(7x-2)-7x(7x-2)+(7x-2)²=

(7x-2)(5-2x-7x+7x-2)=(7x-2)(3-2x)

f)(y-6)³+(y+1)(y-6)²-(5-3y)(y-6)²=

(y-6)²(y-6+y+1-5+3y)=(y-6)²(5y+2)
