Question 999760
 Find the error in each of the following and provide an explanation of the mistake made.
a). 𝑥^2 + 25 = (𝑥+5)(𝑥+5)
If you FOIL the two factors you have you get: x^2+10x+25,
x^2 + 25 does not have any real roots
:
b). 10𝑥^3+15𝑥^2+5𝑥 = 5𝑥(2𝑥^2+3𝑥) it should be 5x(2x^2 + 3x + 1)
:
c). 𝑥^2 − 2𝑥 + 24 = (𝑥−6)(𝑥+4) if you FOIL this you get x^2 - 2x - 24 (-6*4)
equation does not have any real roots
