To convert a quadratic<span> from y = ax</span>2<span> + bx + c </span>form<span> to </span>vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2<span> - 4x + 5 into</span>vertex form<span>, and state the </span>vertex<span>.
Mark me as brainliest if I helped:)</span>

Answer:

The real zeros of f(x) are x = 0.3 and x = -3.3.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$ .

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

In this problem, we have that:

$f(x) = x^{2} + 3x - 1$

So

$a = 1, b = 3, c = -1$

$\bigtriangleup = 3^{2} - 4*1*(-1) = 13$

$x_{1} = \frac{-3 + \sqrt{13}}{2*1} = 0.3$

$x_{2} = \frac{-3 - \sqrt{13}}{2*1} = -3.3$

The real zeros of f(x) are x = 0.3 and x = -3.3.

please help me with this problem this question asks for the angle measure and if the lines are tangent

yaroslaw [1]

step 1

we have that

44=(1/2)[180-arc} ------> by exterior angle

solve for arc

88=180-arc

arc=180-88

arc=92 degrees

give me a minute to draw a figure with letters to better understand the problem

we have that

x+?=180 degrees -------> by form a linear pair (supplemenatry angles)

x=arc=92 degrees ------> by central angle

so

?=180-92

?=88 degrees

therefore

<h2>the missing angle is 88 degrees</h2>
