Answer:

$2 {x}^{2} - 6x - 1 = 0 \\ a = 2 \: \: \: b = - 6 \: \: \: c = - 1 \\ \\ x = \frac{6\binom{ + }{ - } \ \sqrt{ {6}^{2} - 4(2)( - 1)} }{2 \times 2} \\ \\ x = \frac{6 \binom{ + }{ - } \sqrt{44} }{4} \\ x = \frac{6 + \sqrt{44} }{4} \\ \\ or x = \frac{6 - \sqrt{44} }{4}$

I hope that is useful for you :)

Which is the correct algebraic expression after combining like terms? 6+8x-7-x

Anarel [89]

Answer:

7x -1 is correct after combining like terms

Step-by-step explanation:

6+8x-7-x

To simplify algebraic expression we combine like terms

In the given expression

-x or -1x are same

8x and -1x are like terms

6 and -7 are also like terms

8x-1x= 7x

6 - 7 = -1

So 7x -1 is correct after combining like terms

What is 2 1/8 take away 1/2

goblinko [34]

The equation is $2\frac{1}{8} - \frac{1}{2}$ .

1/2 is equivalent to 4/8, and 2 1/8 is equal to 17/8. (two full sets of 8 + 1 = 8 + 8 + 1, or 17)

The new equation is $\frac{17}{8} -\frac{4}{8}$ . Subtract the numerators.

17 - 4 = 13 or 13/8

The improper fraction $\frac{13}{8}$ simplifies to $1\frac{5}{8}$ .

<h2>Answer:</h2>

$1\frac{5}{8}$

Hope this helps :)

Solving quadratic equations by factoring <br> m(m-3)=0

KatRina [158]

Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3
