Tema triangulo rectangulo resolver porfa estoy en examen me queda 10 minuto

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

faster, im not sure why but i know it is faster

- (2, -7)

- lines r and s and lines t and u must be parallel
