Question

Doar d-ul. Multumesc :)

Answer 1

5x^2-3x+1=y
4x^2+x-3=y

5x^2-3x+1 = 4x^2+x-3
x^2 - 4x +4 =0
(x-2)^2=0
x-2=0
x=2

y= 5*2^2-3*2+1=20-6+1=15

Answer 2

^= puterea (daca nu stiai)

5x^2-3x1=y
4x^2+x-3=y

~•~


5x^2-3×+1=4x^2+x-3
x^2-4x+4=0
(x-2)^2=0
x-2=0
x=0+2
x=2

● x=2 ●

~•~

y=5*2^2-3*2+1
y=20-6+1
y=14+1
y=15

● y=15 ●

~•~


Raspuns = y=15, x=2

Sper ca te-am ajutat!
