Answer:
The x-intercepts of the quadratic equation: x = -1 , x = -2/3
See explanation below
Step-by-step explanation:
The question is incomplete as the quadratic equation is missing. I would show you how to find the x intercept of a quadratic equation using the factors
Quadratic equation is in the form: ax² + bx + c =0
Where a, b and c are constant
Let's consider the quadratic equation below to solve the question:
2x² + 5x + 3 = 0
By Factoring the expression: (+2) + (+3) = 5; (+2) ×(+3) = 6
2x² + 2x +3x + 3 = 0
2x(x+1) +3(x+1) = 0
(2x + 3) (x+1) = 0
(2x + 3) and (x+1) are the factors of the quadratic equation.
We would equate both to zero to find x-intercepts
2x + 3 = 0 or x+1= 0
2x = -3 or x = -1
x = -2/3 or x = -1
The x-intercepts of the quadratic equation: x = -2/3 or x = -1
The The x-intercepts of the quadratic starting with lower value:
x = -1 , x = -2/3
