Question 12. ).
Solve:
- 5x + 5 + 4x^2 = 0
Simplify both sides:
4x^2 - 5x + 5 = 0
Step 2.): Use Quadratic Formula:
a = 4, b = - 5, c = 5
x = - b +/- sqrt b^2 - 4ac/2a
x = - ( - 5) +/- sqrt ( - 5)^2 - 4(4)(5) / 2(4)
x = 5 +/- sqrt - 55/8

Hope that helps!!!!! : ) sorry couldn't help with the rest. My brain has to rejuvenate, at a stand still right now.
