Answer:

-6 ± √78\6 [0.47196014..., -2.47196014... = x]

Step-by-step explanation:

The roots [zeros] are the x-values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x.

Answer:

x = 1 + √74/6 or x = 1 - √74/6

Step-by-step explanation:

Points to remember

Zeros of a quadratic equation ax² + bx + c = 0

x = [-b ± √(b² - 4ac)]/2a

<u>To find the zeros of given quadratic equation</u>

It is given that,

6x² +12x - 7 = 0

Here a = 6, b = -12 and c = -7

x = [-b ± √(b² - 4ac)]/2a

 =  [-12 ± √(12² - 4*6*(-7))]/2*6

 = [12 ± √(144 +168 )]/12

 =  [12 ± √312]/12

 = [12 ± 2√74]/12

 = 1 ± √74/6

x = 1 + √74/6 and x = 1 - √74/6

The factor of the given equation  8x^{2} -4x-84 will be  4(x+3)(2x-7)

<h3>What will be the factor of the given equation?</h3>

Given equation is 8x^{2} -4x-84

Now taking 2 commons from the equation

4(2x^{2} -x-21)

now splitting the equation we get

4(2x^{2} +6x-7x-21)

4(2x(x+3)-7(x+3))

4(x+3)(2x-7)

Thus the factor of the given equation  8x^{2} -4x-84 will be  

4(x+3)(2x-7)

Is each expression equivalent to 2x^2 - 50?
puteri [66]
We would first determine how to solve this, and then from there, we would then see whether the following answer would be the correct answers.

2x^2 -  50 \\ \\ Pull \ out \ like \ factors : \\ &#10;&#10;   2x^2 - 50  =   2 * (x^2 - 25) \\ \\    Factoring: \\    x^2 - 25 \\ \\ (your \  answer)...\\ \\   2 * (x + 5) * (x - 5)

Now, we can determine whether the say "yes" or "no" to the following answers.

<span>a 2(x-5)(x+5) = YES
b -2(x+5)(x+5) = NO
c -2(5-x)(x+5) = NO</span>
