To find how many times the quadratic function intersects the x-axis, set y = 0
y = x^2+10x+25
0 = x^2+10x+25
Factor the right hand side
0 = (x+5)(x+5)
x + 5 = 0
x = - 5
Therefore, the quadratic equation intersects the x-axis at one point (x = -5)
Hey is there a paragraph or a little story to go with this I think I can help!
Answer:
Step-by-step explanation:
The given radical expression is;
We multiply both the numerator and the denominator by the conjugate of
which is
The denominator is now difference of two squares;
Simplify:
