Complete the square for 5x^2-30x=5
Nikitich [7]

Solve for x over the real numbers: by completing the square:

5 x^2 - 30 x = 5

Divide both sides by 5:

x^2 - 6 x = 1

Add 9 to both sides:

x^2 - 6 x + 9 = 10

Write the left hand side as a square:

(x - 3)^2 = 10

Take the square root of both sides:

x - 3 = sqrt(10) or x - 3 = -sqrt(10)

Add 3 to both sides:

x = 3 + sqrt(10) or x - 3 = -sqrt(10)

Add 3 to both sides:

Answer: | x = 3 + sqrt(10) or x = 3 - sqrt(10)

What additional information do you need to prove that ∆LMO ≅ ∆LNO by the HL Theorem? ∠NLO ≅ ∠MLO ∠MOL ≅ ∠NOL
FromTheMoon [43]
The hypotenuse leg theorem states that any two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.
The triangles ΔLNO and ΔLMO have the same leg Lo, therefore you need the equality of hypotenuses LM=LN.

lions [1.4K]

Step-by-step explanation:

4h+6h2+1−(5h2−8h4+6)

=4h+6h2+1+−1(5h2−8h4+6)

=4h+6h2+1+−1(5h2)+−1(−8h4)+(−1)(6)

=4h+6h2+1+−5h2+8h4+−6

=4h+6h2+1+−5h2+8h4+−6

=(8h4)+(6h2+−5h2)+(4h)+(1+−6)

=8h4+h2+4h+−5 <- Answer
