<u>Add up as fractions:</u>
- 1/2 + 2/5 = Common denominator is 2*5 = 10
- 5/10 + 4/10 =
- 9/10
Option D
Step 1 should be
Bring the constant to the other side and divide the whole equation with 6 resulting to
x2 + 4x = -7/6
Step 3 should be
Complete the square by dividing the coefficient of x by 2, squaring it and adding the result to both sides of the equation.
x2 + 4x + 4 = -7/6 + 4
Step 4 should be
Factor the quadratic equation and simplify
(x+2)2 = -17/6
Step should be
Get the square root of booth sides and solve for the values of x
x+2 = +-√(102) / 6
So,
x = -2 + √(102) / 6 and x = -2 - <span>√(102) /3
