Answer:
I can't see Mathieu's work but I will show the right steps and maybe you can find where Mathieu went wrong.
f(x)=x^2+4x+3
f(x)=(x+3)(x+1) Since 3*1=3 and 3+1=4
The x-intercepts can be found by setting y to 0 and solving for x
(in other words replace that f(x) thing with 0 and solve for x)
0=(x+3)(x+1)
Now set both factors equal to 0
x+3=0 or x+1=0
x =-3 x=-1
The x-intercepts are at (-3,0) and (-1,0)
<h3>A circle

passes through point (2, -5) is true</h3>
<em><u>Solution:</u></em>
<em><u>Given equation of circle is:</u></em>

Given statement is:
A circle
passes through point (2, -5)
We have to say whether the statement is true or false
<em><u>Substitute x = 2 and y = -5 in given equation</u></em>

The point (2 , -5) satisfies the given circle equation
Thus the statement is true
