What is not another name for the root of an equation?
Determine the solutions of the quadratic equation x2 + 4x + 1 = –2
X = 1, x = 4
X = 3, x = –2
X = 2, x = –2
X = –3, x = –1
Which is the corresponding quadratic equation whose solutions are also the zeros of the function graphed below?
X^2 – x + 6 = 0
–x^2 – x + 6 = 0
X^2 + x + 6 = 0
X^2 + x – 6 = 0
The surface area of a right circular cone with a slant height if 5cm can be modelled by the function SA(r)= πr2 + 5πr, where SA(r) is the surface area in cm2 and r is the radius in cm. What is the root of the function?
What are the solutions to the equation f(x) = x2 – 25 (hint: think difference of squares)
