Hello:
3x²+5x+2=0
delta = (5)²-4(3)(2)=1
x =( -5 <span>±1)/6
x= -2/3 or x=-1
t4-81=(t²)² -9² = (t²-9)(t²+9) =(t-3)(t+3)(t²+9)....(answer B)</span>
Is their a picture that you’re referring to ?
If you’re asking how much do you need to make right angles it should be 90 degrees
Answer:
An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction.S

M = (N-2)/N
M = N² - 2N
N² - 2N - M = 0
To find N we need to use quadratic formula.
For our equation x = N, a=1, b= -2, c= -M
