Answer:
x=1+√3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x^2+6=12x+18
Step 1: Subtract 12x+18 from both sides.
6x^2+6−(12x+18)=12x+18−(12x+18)
6x^2−12x−12=0
For this equation: a=6, b=-12, c=-12
6x^2+−12x+−12=0
Step 2: Use quadratic formula with a=6, b=-12, c=-12.
x=−b±√b2−4ac/2a
x=−(−12)±√(−12)2−4(6)(−12)/2(6)
x=12±√432/12
x=1+√3

Answer:
2
Step-by-step explanation:
Following the order of operations as set out in PEMDAS
6² - 36 ÷ 3² × 4 - 18 ( no parenthesis so evaluate exponents )
= 36 - 36 ÷ 9 × 4 - 18 ( multiplication/ division, evaluate from left to right )
= 36 - 4 × 4 - 18
= 36 - 16 - 18
= 20 - 18
= 2
