Question

10(x+1)+ x(10x+(x+1))=252​

Answer 1

Answer:

10(x+1)+x(10x+(x+1))=252 (Given)

or 10x+10+x(11x+1)=252

or 10x+10+11x²+x=252

or 11x²+11x–242=0

» x²+x–22=0

Using the quadratic formula, i.e.,

$x = \frac{ - b± \sqrt{b {}^{2} - 4ac } }{2a}$

Therefore,

$x = \frac{ - 1± \sqrt{(1) {}^{2} - 4(1)( - 22) } }{2(1)}$

$x = \frac{ - 1± \sqrt{89} }{2}$

And Thus, the values of x are:

$∴ \: x = \frac{ - 1 + \sqrt{89} }{2} \: or \: \frac{ - 1 - \sqrt{89} }{2}$
