Question

factorisarion of expression y2 - 7y + 12 is​

Answer 1

Answer:

(y-3) (y-4)

Step-by-step explanation:

y² - 7y + 12

= y²- 4y - 3y + 12

= y (y - 4) -3 (y - 4)

= (y - 3) (y-4)

Answer 2

$\huge {\boxed {\mathbb {QUESTION}}}$

factorisarion of expression

${y}^{2} - 7y + 12$

$\huge {\boxed {\mathbb {ANSWER}}}$

$\implies {y}^{2} - 7y + 12$

$Factors=\\-4y,-3y$

$\implies {y}^{2} - 4y -3y+ 12=0$

$\implies y(y-4)-3(y-4)=0$

$\implies (y-4)(y-3)=0$

$\implies y-4=0\:or\:y-3=0$

$\implies{\boxed {\boxed {y=4\:or\:y=3}}}$
