4x^2+2x-1=0 in quaratic equations
Viktor [21]

Answer:

Step-by-step explanation:

"quaratic" should be "quadratic."

The coefficients of this quadratic are 4, 2 and -1.  Thus, the discriminant is

b^2 - 4ac, or here, 4 - 4(4)(-1) = 20

Since the discriminant is positive, our quadratic has two real, different roots.

                                -2 ± (√4)(√5)

The roots are:  x = ---------------------

                                       2(4)

                                    -1 ± √5

This reduces to   x = ---------------

I know the answer to this, but how would you solve it? What relationships would you use?
SSSSS [86.1K]

Answer:

131°

Step-by-step explanation:

The central angle in the triangle is 180 - 41 - 41 = 98

which makes the intercepted arc 98

the big arc below is then 360 - 98 = 262

x is an inscribed angle which is half of the arc

1/2(262) = 131

A and b are positive integers and a - b = 2. Evaluate the following:<br> 3b/3а
AlexFokin [52]

Answer and Step-by-step explanation:

a - b = 2

\frac{3b}{3a} = \frac{b}{a}

b = a - 2

a = b + 2

______________

b = b + 2 - 2

b = b

______________

______________

a = a - 2 + 2

a = a

______________

If a equals 0, then the expression is undefined.

If b = 0, then the expression is 0.

There are infinite number of solutions when a is not 0 and the numbers are positive.
