-18 7 11 No solution. The variable is divided out. 20 Question 13
Write the quadratic equation in general form.
4×2 = 8 – 9x
4×2 + 9x + 8 = 0 4×2 + 9x = -8 4×2 – 9x – 8 = 0 -4×2 + 9x – 8 = 0 4×2 + 9x – 8 = 0 Question 14
Solve the quadratic equation by factoring.
x2 – 6x + 5 = 0
-1, 5 -1,-5 1,-5 1,5 6,5 Question 15
Solve the quadratic equation by factoring.
x2 + 8x + 16 = 0
4 -1/4 -4 ±4 1/4 Question 16
Solve the equation by extracting square roots.
(x+6)2 = 5
6 + √5 -6 ± √5 -6 -√5 6 ± √5 -6 + √5 Question 17
Use the Quadratic Formula to solve
x2 + 20x + 98 = 0
x = -8, x = -12 x = -√2 – 10, x = √2 – 10 x = -√3 – 10, x = √3 – 10 x = 10, x = -10 x = -√2 – 9, x = √2 – 9 Question 18
Write the complex number in standard form.
√ -9
