2x^2 + 8x - 12 = 0..divide by 2
x^2 + 4x - 6 = 0
x^2 + 4x = 6...add 4 to both sides of the equation
x^2 + 4x + 4 = 6 + 4
(x + 2)^2 = 10....<== ur constant is 10
x + 2 = (+-)sqrt 10
x = -2 (+ - ) sqrt 10
x = -2 + sqrt 10
x = -2 - sqrt 10
Answer:
how you would keep your math teacher focused
Step-by-step explanation:
try sending your teacher reminder emails, or put some sticky notes on their desk
3(2+x)
open the parenthesis
= 6 + 3x
3(2+x) = 6 + 3x
Hence the statement of equality is true
H is the correct option
