Factor the following<br>(a²+b²)²-18(a²+b²)-88

navik [9.2K]

Answer:

$\rm\displaystyle( {a}^{2} + {b}^{2} - 22)( {a}^{2} + {b}^{2} + 4)$

Step-by-step explanation:

we would like to factor the following:

$\rm\displaystyle ( {a}^{2} + {b}^{2} {)}^{2} - 18( {a}^{2} + {b}^{2} ) - 88$

let a²+b²=x

thus substitute:

$\rm\displaystyle x {}^{2} - 18x- 88$

rewrite the middle term as 4x-22x:

$\rm\displaystyle x^{2} + 4x - 22x - 88$

factor out x:

$\rm\displaystyle x( x^{} + 4)- 22x - 88$

factor out -22:

$\rm\displaystyle x( x^{} + 4)- 22(x + 4)$

group:

$\rm\displaystyle( x- 22)(x + 4)$

substitute back:

$\rm\displaystyle( {a}^{2} + {b}^{2} - 22)( {a}^{2} + {b}^{2} + 4)$

and we are done!

Step-by-step explanation:

Complete Question

One gallon of gasoline in Buffalo, New York costs $2.29. In Toronto, Canada, one liter of gasoline costs $0.91. There are 3.8 liters in one gallon.

a. How much does one gallon of gas cost in Toronto? Round your answer to the nearest cent.

b. Is the cost of gas greater in Buffalo or in Toronto? How much greater?

Solution

Given

Cost of one gallon of gasoline in Buffalo, New York $= 2.29$ dollars

Cost of one liter of gasoline in Toronto, Canada $= 0.91$ dollars

One gallon $= 3.8$ liters

Thus, $1$ liter $= \frac{1}{3.8}$ gallons

a) Cost of $\frac{1}{3.8}$ gallons of gasoline in Toronto, Canada $= 0.91$ dollars

Cost of $1$ gallons of gasoline in Toronto, Canada

$=3.8 * 0.91\\= 3.458\\= 3.46$

b) Difference in price for a gallon of gas for the two locations

$3.46 - 2.29 \\= 1.17$

Cost of one gallon of gas is Toronto, Canada is higher by $ $1.17$
