Answer:

Step-by-step explanation:

You can make a table of values by plugging in values to x^2+4.

If x=1 the answer is 5

If x=2 the answer is 8

If x=3 the answer is 13

If x=4 the answer is 20

If x=5 the answer is 25.

And we have a table of values!

Solve for x in the equation x squared + 2 x + 1 = 17.

Papessa [141]

Answer:

$x = - 1 + \sqrt{17}\\and\\x = - 1 - \sqrt{17}\\$

Step-by-step explanation:

given equation

$x^2 +2x +1 = 17$

subtracting 17 from both sides

$x^2 +2x +1 = 17\\x^2 +2x +1 -17= 17-17\\x^2 +2x - 16 = 0\\$

the solution for quadratic equation

$ax^2 + bx + c = 0$ is given by

x = $x = -b + \sqrt{b^2 - 4ac} /2a \\\\and \ \\-b - \sqrt{b^2 - 4ac} /2a$

________________________________

in our problem

a = 1

b = 2

c = -16

$x =( -2 + \sqrt{2^2 - 4*1*-16}) /2*1 \\x =( -2 + \sqrt{4 + 64}) /2\\x =( -2 + \sqrt{68} )/2\\x = ( -2 + \sqrt{4*17} )/2\\x = ( -2 + 2\sqrt{17} )/2\\x = - 1 + \sqrt{17}\\and\\\\x = - 1 - \sqrt{17}\\$

thus value of x is

$x = - 1 + \sqrt{17}\\and\\x = - 1 - \sqrt{17}\\$

Sin(a+b) + sin (a-b) = 2 sin a cos b verify the identitiy

Bas_tet [7]

Write out the sum formula for sin
sin(x + y) = sinxcos + sinycosx 

Then expand sin(a + b) + sin(a - b) 
sinacosb + sinbcosa + sinacosb - sinbcosa 
The 2nd and 4th terms cancel and you get 
2sinacosb
