7) factor of x²+ 10x+25 is?
Answers
Answer:
x=-5
Step-by-step explanation:
Considering the equation as ax^2+bx+c=0
where a,b,c are constants
To factorise the equation, b should be divided in 2 parts b1 and b2 such a way that b1*b2=a*c and b1+b2=b.
Thus, x^2+10x+25=0
Comparing with its general equation, a=1, b=10 and c=25.
b1*b2=1*25=25 and b1+b2=10
So,
X^2+5x+5x+25=0
x(x+5)+5(x+50)=0
(x+5)*(x+5)=0
(x+5)^2=0
x+5=0
x=-5
