Identify the coefficients of the terms for 5x^4 - 2x^2 + 8x - 15​

Math each whole number with a rational,exponential expression

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Which function has the domain x> -11? y= x+ 11 +5 y= x-11 +5 y= x+5 - 11 y= x+5 + 11
