Answer:
Therefore the x-intercept of
is
Step-by-step explanation:
Intercepts:
The line which intersect on x-axis and y-axis are called intercepts.
There are two intercepts:
y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.
x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.
For x-intercept of y = 3x² + 6x + 3
put y = 0
Dividing throughout by 3 we get
Which is nothing but in the identity form of (A+B)² = A² +2AB +B²
A = x
B = 1
Therefore Equation becomes
Therefore the x-intercept of
is
