20 =-16t^2+36t
what is the answer

Step-by-step explanation:

16t^2-36t+20=0

a = 16; b = -36; c = +20;

Δ = b2-4ac

Δ = -362-4·16·20

Δ = 16

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

t1=−b−Δ√2at2=−b+Δ√2a

Δ−−√=16−−√=4

t1=−b−Δ√2a=−(−36)−42∗16=3232=1

t2=−b+Δ√2a=−(−36)+42∗16=4032=1+1/4

answer: no
