Answer 2

Answer:

1. x = 6 & -2
2. x = -6
3. x = -4.69 & 4.69

Step-by-step explanation:

Let unknown no. = x

1)

3 + 4x = x² - 9

x² - 4x - 9 - 3 = 0

x² - 4x - 12 = 0

(x-6)(x+2) = 0

x = 6 & x = -2

2)

7(4+x) = -14

4 + x = -2

x = -6

3)

x² + 5 = 27

x² = 22

x = +-√22

x = +√22

= 4.69 (3s.f)

x = -√22

= -4.69 (3s.f)
