Question

The two equations below are equivalent: = Equation A: y= (x + 2)(x+3) Equation B: y= 22 +52 + 6 a. Which equation helps find the -intercepts most efficiently? [ Select] b. Which equation helps find the -intercept most efficiently? [Select ]

Answer 1

Here, we want to select the equations that can help find the intercepts efficinetly

The general form of a quadratic trinomial is;

$y=ax^2\text{ + bx + c}$

c here is the y-intercept

The equation that can help find the y-intercept effectively is the second one; equation b

For the x-intercept, we only need to equate each of the brackets to zero and thus, the equation that can help find the x-intercept effectively is the first one
