For this exercise find all real solutions of 3y2 32210 and b

For this exercise, find all real solutions of 3(y² -3)²-2=10 and be sure to check your answer. Please make your solution editable so that i can copy and paste

Solution

3(y^2-3)^2 -2=10.

3(y^2-3)^2=10+2

(y^2-3)^2=(12/3)

(y^2-3) = (4)

y^2-3=2 and y^2-3=-2

y^2=2+3 and y^2=-2+3

y^2=5 and y^2=1

y = 5 and y=-5 and y=1 and y=-1
