Answer:
x= 5.55 and 0.45
Step-by-step explanation:
Quadratic Equation = (-b±√b²-4(a)(c))÷2(a)
Get equation = to 0 by subtracting the 3 on the right side of the = sign
2x² - 12x + 5
Identify the variables
a=2
b=-12
c=5
Put them into the quadratic equation
(-(-12)± √-12² - 4(2)(5))÷2(2)
Simplify
(12 ±√144 - 40)÷4
(12±√104)÷4
Now split into 2 equations (one with addition one with subtraction) because of the ± then continue simplifying
(12 - √104)÷4 (12 + √104)÷4
(12 - 10.198039)/4 (12 + 10.198039)/4
5.54950975 0.45049025
Round
5.55 0.45
Answer:
(1) 9
(2) 
(3) 6(
)
Step-by-step explanation:
From the question,
(1) (
)²
Applyin the law of multiplication of surds
(
)² = (
(2) (
)× (
) =
Also applying the the law of multiplication of surd
(
)×(
) = (
) ( This is an irational answer)
∴ (
)×(
) = 
(3) 2(
)×3(
)
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×(
)×(
)
6×(
) = 6(
