Question

Find the points of intersection of x-Axis of the graph of
x² + 5x + 6​

Answer 1

Answer:

x= -2 and x= -3

Step-by-step explanation:

the curve touch x axis means y=0

then

x²+5x+6=0

=> x²+3x+2x+6

=>(x+3)(x+2)

Answer 2

Answer:

Every equation which is in terms of 'x' will intersect x-axis at the roots of the equation.

Touching x-axis means the points where the equation value becomes zero.

Given the equation x 2 −5x+6=0

⇒x 2 −2x−3x+6=0

x(x−2)−3(x−2)=0

Factorising it , we get

(x−2)(x−3)=0

⇒x=3 , 2 -Ans
