Solve the equation : x^(2)+5=3(x^(2)-3)

Mathematics
1 answer:
Fittoniya [83]3 years ago
6 0

Answer:

x = ± 2

Step-by-step explanation:

Given

x² + 5 = 3x² - 3 ( subtract x² + 5 from both sides )

0 = 2x² - 8 ( add 8 to both sides )

8 = 2x² ( divide both sides by 2 )

4 = x² ( take the square root of both sides )

x = ± \sqrt{4} = ± 2

Given the function f(x)=4x^8+7x^7+1x^6+1 What is the value of f(−2)?
qwelly [4]
<span> f(x)=4x^8+7x^7+1x^6+
</span>∴<span> f(-2)=4(-2)^8+7(-2)^7+1(-2)^6+1
</span>∴ <span>f(-2)=(4x256) + (7x-128) + (1x64) +1
</span>∴ <span>f(-2)=1024 - 896 + 64 +1
</span>∴ <span>f(-2)= 193</span>

A system of equations is shown below:
user100 [1]
<span>3x − y = 2

y = 3x - 2

x + y = 6

x + 3x - 2 = 6

4x - 2 = 6

4x = 6 + 2

4x = 8

x = </span>\frac{8}{4}

x = 2

Hence, the x co-ordinate is 2.
