Question

33x²-61x-10

please Explainations​

Answer 1

Step-by-step explanation:

33x^2-61x-10=0

a = 33; b = -61; c = -10;

Δ = b2-4ac

Δ = -612-4·33·(-10)

Δ = 5041

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

We use following formulas to calculate our solutions:

x1=−b−Δ√2ax2=−b+Δ√2a

Δ−−√=5041−−−−√=71

x1=−b−Δ√2a=−(−61)−712∗33=−1066=−5/33

x2=−b+Δ√2a=−(−61)+712∗33=13266=2
