What is a polynomial for the area of a circle with radius(x plus 2) feet?
A = pi()*(x2 + 4x +4) square feet.
What is the quotient of the polynomial 4x exponent four minus x cubed plus 17x squared plus 11x plus 4 when divided by the expression 4x plus 3?
x3-x2+5x-1 with remainder 7, which the final answer would be written as:x3-x2+5x-1+[7/(4x+3)]

(x+7) and (x-3)
What is the discriminant of the polynomial below x2 plus 5x plus 7?
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
What is the value of the discriminant polynomial x2-8?
10
The polynomial y equals x2 - 4x plus 4 has a repeated factor?
y = x2 - 4x + 4 can be factored into y = (x-2)(x-2) The repeated factor is 2.
What is if any are the points of intersection of the parabolas y equals x2 -4x plus 8 and y equals 8x -x2 -14 showing work with explanations?
If: y = x2-4x+8 and y = 8x-x2-14 Then: x2-4x+8 = 8x-x2-14 So: 2x2-12x+22 = 0 Discriminant: 122-(4*2*22) = -32 Because the discriminant is less than 0 there is no actual contact between the given parabolas
