Parent on line needs help ... long time since math
Aunt is 26 years older than niece - the product of their ages = 456 ... so x(x+26) = 456

that's right.
then you expand the left hand side of the equation and you'll have a quadratic equation.

Answer 2

Multiply it out and subtrtact 456 from both sides of the equation and then use quadratic formula to solve

Answer 3

\[-b \pm \sqrt{b ^{2}-4ac}\over2a\]
for your equation, a=1, b=26, c=-456

Answer 4

\[-26\pm \sqrt{26^{2}-(4)(-456)}\over 2\]
You will find that neice is 12 yrs young and aunt is 38 yrs old.
