f) 2a(x-1) + 3b (x-1) - 4(x-1)


Dau coroana!!!
Repede, plss!!

Answer 1

a) 5√3x(x-5) -3√3(x-5)=√3(x-5)(5x -3)

b) 2√2x(2x+3) -4√2 (2x+3)=2√2(2x+3)(x -2)

c) 3√2x (x+2) +6√2(x+2)= 3√2(x+2)(x +2)=3√2(x+2)²

d) 6√5x(x-3) -18√5(x-3)=6√5(x-3)(x -3)=6√5(x-3)²

e) x(a-b) + y(a-b) + 3(a-b)= (a-b)(x + y + 3)

f) 2a(x-1) + 3b (x-1) - 4(x-1)= (x-1)(2a + 3b - 4)

Answer 2

a)(x-5)(5√3x-3√5)
b)(2x+3)(2√2-4√2)
c)(x+2)(3√2x+6√2)
d)(x-3)(6√5x-18√5)
e)(a-b)(x+y+3)
f)(x-1)(2a+3b-4)
