When Pedro solved the equation y = y – 2, he squared both sides,
obtaining y^2 - 5y + 4 = 0. He solved the resulting equation and wrote (1, 4) as
the solution set. He said that both numbers satisfy the equation y^2-5y+4=0.
State what is wrong with his statement.

Step-by-step explanation:
1. he product of the squared integers are wrong. it should be
y²= (y-2)²
y²= y²-4y+4
4y-4=0
pabrainliest po please thanks
