Question

factorise y²-5y+4
solve it fast​

Answer 1

Answer:

Step-by-step explanation:

First, add 4 to each side of the equation to put it into standard

quadratic form:

y2−5y+4=0

= y2−5y=-4

Next, factor as:

(y−1)(y−4)=0

Now, solve each term on the left for 0 :

Solution 1:

y−1=0

Taking 1 to the other side

y−0=1

y=1

Solution 2:

y−4=0

Taking 4to the other side

y−0=4

y=4

The Solution Set Is:

y={1,4}

Pls mark me as the brainliest answer

Answer 2

${y}^{2} - 5y + 4$

${y}^{2} - y - 4y + 4$

$y(y - 1) - 4(y - 1)$

$(y - 1)(y - 4)$

hope it helps you.......
