Question

solve the equ 3y²-y-7=0 and give your answer correct to two decimal places​

Answer 1

Answer:

3y square - y - 7 = 0

3y cube - 7 = 0

3y cube = 0 + 7

3y cube = 7

3y cube ÷ 3 = 7 ÷ 3

y = 1.320006122

y = 1.32

Step-by-step explanation:

First do y and y then you get y cube then take 7 another side then divide both side by 3 then when you do 7 ÷ 3 then you will get 2.3333 ot 2.3 then put that in cube square then when you do that you will get y = 1.320006122 in 2 decimal you get as y = 1.32.
