Answer:

x = - 7

Step-by-step explanation:

1) Add 8 to both sides.

-8x-8=-5x+13

-8x - 8 + 8 = -5x + 13 + 8

2) Simplify

- Add the numbers

-8x - 8 + 8 = -5x + 13 + 8

-8x = -5x + 13 + 8

- Add the numbers

-8x = -5x + 13 + 8

-8x = -5x + 21

3) Simplify

- Combine like terms

-8x + 5x = -5x + 21 + 5x

-3x = -5x + 21 + 5x

- Combine like terms

-3x = -5x + 21 + 5x

-3x = 21

4) Divide both sides by the same factor

-3x + 21

-3x/-3 = 21/-3

6) Simplify

- Cancel terms that are in the numerator and denominator

-3x/-3 = 21/-3

x = 21/-3

- Divide the numbers

x = 21/-3

x = -7

Solve for the zeros of the quadratic function f(x) = 9x² + 6x + 1.

Nezavi [6.7K]

Answer:

$\large\boxed{x=-\dfrac{1}{3}}$

Step-by-step explanation:

$f(x)=9x^2+6x+1\\\\\text{The zeros are for}\ f(x)=0\\\\9x^2+6x+1=0\\\\9x^2+3x+3x+1=0\\\\3x(3x+1)+1(3x+1)=0\\\\(3x+1)(3x+1)=0\\\\(3x+1)^2=0\iff3x+1=0\qquad\text{subtract 1 from both sides}\\\\3x=-1\qquad\text{divide both sides by 3}\\\\x=-\dfrac{1}{3}$
