The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =

andrey2020 [161]

we have

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

Find the roots

Equate the function to zero

$x^{2}-2x-3=0$

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

$x^{2}-2x=3$

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

$x^{2}-2x+1=3+1$

$x^{2}-2x+1=4$

Rewrite as perfect squares

$(x-1)^{2}=4$

Square root both sides

$(x-1)=(+/-)2$

$x=1(+/-)2$

$x=1+2=3$

$x=1-2=-1$

therefore

the answer is

$x=3$

Help please im stuck

If the two equations have the same solution, they will have the same x value that makes them true. So solve for x for both equations and see if they are equal:

$8x=87 \\
x=10.875$

$\frac{2}{3} x+ \frac{3}{4} =8 \\
 \frac{2}{3} x=7.25 \\
x=10.875$

Because both equations have the same x value, they have the same solution.
