Bill and susan have ages that are consecutive odd integers.The product of their ages 438.Which equation could be used to find bi
zhuklara [117]

Answer:

4 x^{2} + 8 x - 435=0

Step-by-step explanation:

Let x be any natural number

Let the age of Bill= 2 x+ 1  years (Since age is odd integer)

Than, age of a Susan= 2 x + 3 years

Since ages are consecutive odd integers

According to question

(2 x+1)(2 x+ 3)= 438

4 x^{2} + 8 x + 3 = 438

4 x^{2} + 8 x + 3 - 438 =0

4 x^{2} + 8 x - 435=0

This equation can be used to find the ages of both

Hence, the correct answer is 4 x^{2} + 8 x - 435=0
