Solve for w. 5w−3+3w=7w2−3w

Question

 i dont kniw how to do thuis sio help me

Answer 1

5w - 3 + 3w = 7w² − 3w

8w - 3 = 7w² - 3w

-3 = 7w² - 11w

0 = 7w² - 11w + 3

 

The roots are irrational. Use the Quadratic Formula

Answer 2

5w − 3 + 3w = 7w² − 3w

 

Combine like terms

     8w - 3 = 7w² − 3w

Bring all terms to the right side so you have a zero on the left:

     0 = 7w² - 11w + 3

Factor using ac method

     0 = (7w-3)(w-1)

Solve each factor for w to get the two answers

     (7w-3) = 0

     (w-1)=0
