I need to find out the points
1 answer:
Answer:
The roots are x = 1 and x = 3
Step-by-step explanation:
The roots of a polynomial are those x-values for which the polynomial renders zero. Therefore, you need to look at the points of the parabola that intersect the x-axis (since they correspond to y=0:
Please see attached image for the location of the two points that cross the x-axis. They are located at (1, 0) and at (3, 0), therefore, the roots of the parabola are: x = 1 and x = 3.

<h3>Factoring quadratic equation</h3>Given the quadratic equation below
f(x) = x^2 - 3x - 4
Factorize
f(x) = x^2 - 4x + x - 4 = 0
f(x) = x(x - 4) + 1(x - 4) = 0
(x+1)(x-4) = 0
Hence the factors of the trinomial to the given quadratic expression are (x+1) and (x-4)
