Question

3y2=15y by formula method

Answer 1

We have,

$\qquad \: \: 3 {y}^{2} = 15y \\ \\ \implies 3 {y}^{2} - 15y = 0 \\ \\ \implies 3y(y - 5) = 0 \\ \\ \implies 3y = 0 \: \boxed{or} \: y - 5 = 0 \\ \\ \implies y = 0 \: \: \: \boxed{or} \: y = 5$

Answer 2

Answer:

▶3y²=15y

▶3y²-15y=0

▶3y(y-5)=0

▶y-5=0

▶y=5
