Expand the following:

-(-8 m - 4 n + 7)

-(7 - 8 m - 4 n) = -7 - -8 m - -4 n:

-7 - -8 m - -4 n

-(-8) = 8:

-7 + 8 m - -4 n

Find the solution set.<br> 8x^2+7x-1=0
Likurg_2 [28]

Answer:

x = - 1, x = \frac{1}{8}

Step-by-step explanation:

Given

8x² + 7x - 1 = 0 ← in standard form

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 8 × - 1 = - 8 and sum = + 7

The factors are + 8 and - 1

Use these factors to split the x- term

8x² + 8x - x - 1 = 0 ( factor the first/second and third/fourth terms )

8x(x + 1) - 1(x + 1) = 0 ← factor out (x + 1) from each term

(x + 1)(8x - 1) = 0

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

8x - 1 = 0 ⇒ 8x = 1 ⇒ x = \frac{1}{8}

jekas [21]

6 is what you're dividing by so it goes on top as the numerator and x + y is the denominator: \frac{6}{x+y}
