Find the zeros of the function by rewriting in intercept form.Y=2X^2-4x

y=2C^2-11X-21

I need the answer and the work please.

Answers

Answer 1

Answer: The intercept form is $y=a(x-p)(x-q)$ where p, q - the zeroes of a function.

1.
$y=2x^2-4x \ny=2x(x-2) \ny=2(x-0)(x-2) \n\hbox{the zeroes - }\boxed{x=0 \ and \ x=2}$

2.
$y=2x^2-11x-21 \ny=2x^2-14x+3x-21 \ny=2x(x-7)+3(x-7) \ny=(2x+3)(x-7) \ny=2(x+(3)/(2))(x-7) \n y=2(x-(-(3)/(2)))(x-7) \n\hbox{the zeroes - }\boxed{x=-(3)/(2) \ and \ x=7}$

a = $(v - u)/(t)$

A barge travels twice as fast when it is empty as when it is full. If it travels 20 miles northwith a cargo, spends 20 minutes unloading, and returns to its original port
empty, taking 8 hours to complete the entire trip, what is the speed of the barge when it
is empty?

Answers

V1=(empty)=2*v2(full)
20+20 (go+return)
t1+t2=8hour-20’(1/3 hour)=23/3hour
t1=23/3-t2
v1*t1+v2*t2=20+20
2v2*(23/3-t2)+v2*t2=40
2v2*23/3-2v2*t2+v2t2=40
2v2*23/3-v2t2=40
2v2*23/3-20=40
2v2*23/3=60
v2=60/46/3=180/46=90/23
v1=2*90/23=180/23
