Trish is solving for the zeros of the quadratic function f(x) = 2x2 – 3x + 3.
x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction
x = StartFraction negative (negative 3) plus or minus StartRoot (negative 3) squared minus 4 (2)(3) EndRoot Over 2 (2) EndFraction
x = StartFraction 3 plus or minus StartRoot b 9 + 32 EndRoot Over 4 EndFraction
x = StartFraction 3 plus or minus StartRoot 41 EndRoot Over 4 EndFraction
Did Trish find the correct zeros of this function? Explain.
A). Yes, those are the two real number zeros.
B). No, the two real number zeros are StartFraction negative 3 plus or minus StartRoot 41 EndRoot Over 4 EndFraction.
C). No, the two real number zeros are StartFraction 3 plus or minus StartRoot 41 EndRoot Over negative 4 EndFraction.
D). No, the function has no real number zeros.
