Answer:
We are given, m∠B=90
o
AB=(x−3) cm
BC=(x+4) cm
AC=(x+6) cm
x=?
From pythagoras theorem,
AC

=AB

+BC

(x+6)

=(x−3)

+(x+4)

∴ x

+12x+36=x

−6x+9+x

+8x+16
∴ x

+12x+36=2x

+2x+25
∴ 2x

−x

+2x−12x+25−36=0
∴ x

−10x−11=0
∴ x

−11x+x−11=0
∴ x(x−11)+1(x−11)=0
∴ (x+1)(x−11)=0
So, x+1=0 or x−11=0
x=−1
or
x=11
