consider the function f(x) = x2 2x – 15. what are the x-intercepts of the function? left-most x-intercept: ( , 0) right-most x-i

eimsori [14]

we have

$f(x)=x^{2} +2x-15$

we know that

The x-intercept is the value of x when the value of the function is equal to zero

so

in this problem

Find the roots of the function

equate the function to zero

$x^{2} +2x-15=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2} +2x=15$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} +2x+1=15+1$

$x^{2} +2x+1=16$

Rewrite as perfect squares

$(x+1)^{2}=16$

Square root both sides

$(x+1)=(+/-)\sqrt{16}$

$(x+1)=(+/-)4$

$x=-1(+/-)4$

$x1=-1+4=3$

$x2=-1-4=-5$

$x^{2} +2x-15=(x-3)(x+5)$

therefore

<u>the answer is</u>

the x-intercepts are the points $(3,0)$ and $(-5,0)$

La suma del cuadrado de un número más el triple del mismo número es igual a dieciocho. Encuentra dicho número.

Genrish500 [490]

If the sum of the square of a number plus the triple of the same number equals eighteen, the required numbers are 3 and -6

Let the unknown number be x

The square of the number is expressed as x²

Triple of the unknown number will also be expressed as 3x

Taking the sum of both numbers and equating it to 18 will give;

$x^2 + 3x = 18\\x^2 + 3x - 18 =0$

Factorize the resulting equation:

$x^2+3x -18=0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x= 3 \ and \ -6$

Hence the required numbers are 3 and -6
