Sovle for x . 4(x-4)=36

Katena32 [7]

Answer:

below

Step-by-step explanation:

$x.4 ( x-4) = 36 \\$

$4x(x-4) = 36 \\$

$4x^{2} - 16x = 36$

add -36 to both sides

$4x^{2} - 16x - 36 = 36 -36 \\4x^{2} -16x - 36 = 0$

divide both sides by 2

$\frac{4x^{2} - 16x - 36 }{4} = 0/4$

$x^{2} -4x-9 = 0$

This is a quadratic equation

let's solve it by graphing it

The solution are the x-coordinates of the intersection points

The x-coordinates of the intersection points are approximatively -1.6 and 5.6

What are the solutions to the equation? b^2 − 10b=39

erik [133]

1)

$b^2-10b=39\\\\(b-5)^2-25=39 \ |+25 \\\\ (b-5)^2=64\\\\(b-5)^2=(\pm 8)^2\\\\ b-5=-8 \ or \ b-5=8 \\\\ b=-3 \ or \ b=13$

2)
-10b = 3b - 13b

$b^2-10b=39\\\\b^2+3b-13b-39=0\\\\b(b+3)-13(b+3)=0\\\\ (b+3)(b-13)=0\\\\ b+3=0\ or \ b-13=0 \\\\ b=-3\ or \ b=13$
