Answer:

x = 3

x = 2

x= ± √ -1

Step-by-step explanation:

((((x^4)-(5•(x^3)))+7x^2)-5x)+6 = 0

((((x^4) - 5x^3) + 7x^2) - 5x) + 6 = 0

Dividing : x^4-5x^3+7x^2-5x+6

("Dividend")

By : x-3 ("Divisor")

Quotient : x^3-2x^2+x-2 Remainder: 0

Dividing : x^3-2x^2+x-2

("Dividend")

By : x-2 ("Divisor")

Quotient : x^2+1 Remainder: 0

(x^2 + 1) • (x - 2) • (x - 3) = 0

x^2+1 = 0

x^2 = -1

x = ± √ -1

x-2 = 0

x = 2

x-3 = 0

x = 3

Solve the inequality -2≥4p+6+4

Alchen [17]

Hi there

-2 ≥ 4p + 6 + 4

-2 ≥ 4p + 10

4p +10 ≤ -2

Now subtract 10 form both sides

4p + 10 - 10 ≤ -2 - 10

4p ≤ -12

Divide by 4

4p/4 ≤ -12/4

p ≤ -3

I hope that's help:)

1. If x=3-√3, prove that x² +36 x² = x²

valentina_108 [34]

Answer:

we get $x^2=12-6\sqrt{3}$

Step-by-step explanation:

We are given: $x=3-\sqrt{3}$

We need to find $x^2$

Note: Since question is not clear, I am assuming that we need to find $x^2$

Solving:

$x=3-\sqrt{3} \\Taking \ square \ on \ both \ sides\\x^2=(3-\sqrt{3})^2\\$

We know that $(a-b)^2= a^2-2ab+b^2$

Using formula and simplifying

$x^2=(3)^2-2(3)(\sqrt{3})+(\sqrt{3})^2\\x^2=9-6\sqrt{3} +3\\x^2=12-6\sqrt{3} \\$

So, we get $x^2=12-6\sqrt{3}$
