Express 7 square as the sum of two consecutive positive numbers.
Alborosie

Answer:

24 and 25

Step-by-step explanation:

From given, we have,

7 square = 49

Let the first positive number be = x

And the second consecutive positive number is = x+1

x + (x + 1) = 49

2x + 1 = 49

2x = 49 - 1

2x = 48

x = 24

the first number x = 24

the second consecutive number x+1  = 24 + 1 = 25

Thus, 7 square = 24 + 25 (the sum of two consecutive positive numbers.)

Factor the following trinomial. (Hint: Solve the equations first.)<br><br> x²-2x-2
Alex_Xolod [135]

Answer:

(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))  

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^{2} -2x-2=0  

so

a=1\\b=-2\\c=-2

substitute in the formula

x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}

x=\frac{2(+/-)\sqrt{12}} {2}

x=\frac{2(+/-)2\sqrt{3}} {2}

x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}

x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}

therefore

x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))
