example of equation transformable into quadratic

Sagot :

1) Find two consecutive even integers whose product is 224.
    First even integer:  x
    Next even integer: x + 2

Equation:  
        (x) (x+2) = 224
Transform to quadratic equation in form ax² + bx + c = 0
        x² + 2x -224= 0

2) A's father is three years more than twice as old her.  The product of their ages is 560.  How old is A?

Let A's age be x
Let A's father's age be 2x + 3
Product of their ages = 560

Equation:
     (x) (2x + 3) = 560

Transform to quadratic equation, ax² + bx + c = 0
     2x² + 3x - 560 = 0
