vaa roggggg am nevoie urgentttt dau coronitaaa​

Answer 1

Răspuns:

2.

C)=9x la puterea 2 +24x+16-(9x la puterea 2 - 4)=9x la puterea 2 +24x+16-9x la puterea 2 +4=24x+20

D)=4x la puterea 2 +20x+25-4(x la puterea 2 - 4)=4x la puterea 2 +20x - 4x la puterea 2 +16=20x+41

E)=16x la puterea 2 - 8x +1-4(4x la puterea 2-9)=16x la puterea 2-8x+1-16x la puterea 2+36=-8x+37

3.

A) =4x la puterea 2 +4x+1-(9x la puterea 2 +24x+16)+9x la puterea 2 +12x+4=4x la puterea 2 +4x+1-9x la puterea 2 - 24x-16+9x la puterea 2 +12x+4=4x la puterea 2 - 8x-11

B)=16x la puterea 2 - 24x+9-(4x la puterea 2 - 20x+25)-(9x la puterea 2 - 24x+16)=16x la puterea 2 - 24x+9-4x la puterea 2 +20x-25-9x la puterea 2 +24-16=3x la puterea 2 - 32+20x

C)=9x la puterea 2 +24x+16-(4x la puterea 2 +28x+49)-(x la puterea 2 +6x+9)=9x la puterea 2 +24x+16-4x la puterea 2 - 28x-49-x la puterea 2 - 6x-9=4x la puterea 2 - 10x-42
