Solve by factoring and i need the steps too !!

IrinaVladis [17]

Answer:

$x_1 = -8\\\\x_2 = 8$

Step-by-step explanation:

To solve this problem use the formula "<u><em>Difference of squares</em></u>":

$(a + b) (a-b) = a ^2 -b ^ 2$

In this problem we have the following equation

$x ^ 2 -64 = 0$

This we can write it in the following way

$x ^ 2 - 8 ^ 2 = 0$

Then if a = x and b = 8 then:

$x ^ 2 - 8 ^ 2 = (x+8)(x-8) = 0$

Then the product of both factors is equal to zero when:

$x+8 = 0\\\\x =-8$

$x -8 = 0\\\\x =8$

A quadratic equation of the form 0=ax^2+bx+c has a discriminant value of -16. How many real numbers solutions does the equation

alina1380 [7]

Answer: 0

Step-by-step explanation:

The disciminant \Delta tells you how many real solutions a quadratic equation has, depending on its sign:

\Delta>0\implies\text{2 solutions}\\\Delta=0\implies\text{1 solution}\\\Delta<0\implies\text{no solutions}

Given:

Fynjy0 [20]

Answer:

Option B is correct.

$\triangle RST \cong \triangle TUR$

Step-by-step explanation:

Given: RSTU is a parallelogram.

By definition of parallelogram, two pairs of opposite sides are congruent in length.

⇒ $TU \cong RS$ and $TS \cong RU$

In triangle RST and triangle TUR

$RS \cong TU$ [Side]

$TS \cong RU$ [Side]

$RT \cong RT$ [Common side]

SSS(Side-Side-Side) postulates states that if three sides of one triangle are congruent to three sides of other triangle, then the triangles are congruent.

then, by SSS postulates we have;

$\triangle RST \cong \triangle TUR$

6 7 8 9 10 TIME REMAINING 59:50 Two positive integers are 3 units apart on a number line. Their product is 108. Which equation c

OLEGan [10]

N and m are numbers 3 units apart

n + 3 = m
n = m - 3

Product:

m(m-3) = 108 (ANSWER)
m^2 - 3m - 108 = 0
(m-12)(m+9)=0

m = 12(greates) and -9(void)

n = m - 3
n = 12 - 3
n = 9

therefore the two numbers are 9 and 12
