Question

y2-18y=-45. What is the solution???

Answer 1

Answer:

${y}^{2} - 18y + 45 = 0 \\ \\ {y}^{2} - 15y - 3y + 45 = 0 \\ \\ y(y - 15) - 3(y - 15) = 0 \\ \\ (y - 3)(y - 15) = 0 \\ \\ y = 3 \: \: \: and \: \: \: y = 15$

Answer 2

Answer:

Step-by-step explanation:

y^2-3y-15y+45=0

y(y-3)-15(y-3)=0

(y-3)(y-15) =0

y-3=0

y=3

OR

y-15=0

y=15
