Background For Teachers: Our place value system is based on a pattern of tens. Each place value increases ten times the value of the place to its right. We use the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 to write any whole number. The symbols are called digits

Given f(x)= (x-5)/3, solve for f^-1(3)

IceJOKER [234]

F-1(x) = (3x + 5) / 3

f-1(3) = (9 + 5) / 3 = 14/3

Factor completely 8x2 − 4x − 84. 4(2x − 3)(x 7) 4(2x 3)(x − 7) 4(x − 3)(2x 7) 4(x 3)(2x − 7).

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

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

What are all the roots of the equation x^2+6x-9

frez [133]

Answer:

x = - 3 ± 3 $\sqrt{2}$

Step-by-step explanation:

given the equation x² + 6x - 9 = 0

We can solve for x using the quadratic formula

x = ( - b ± $\sqrt{b^2-4ac }$ ) / 2a

with a = 1, b = 6 and c = - 9

x = ( - 6 ± $\sqrt{6^2-(4(1)(-9)}$ ) / 2

= ( - 6 ± $\sqrt{36+36}$ ) / 2

= ( - 6 ± $\sqrt{72}$ ) / 2

= ( - 6 ± 6 $\sqrt{2}$ ) / 2

x = - 3 ± 3 $\sqrt{2}$
