Best ResponseYou've already chosen the best response.0if I add 9 to both sides, I get: \[\Large 4{r^2}  9 + 9 = 91 + 9\] please simplify

Best ResponseYou've already chosen the best response.0ok! now I diveide by 4, both sides, so I get: \[\Large {r^2} = \frac{{100}}{4}\]

Best ResponseYou've already chosen the best response.0ok! now we have to take the square root of both sides, so we can write: \[\Large r = \pm \sqrt {25} = ...\]

Best ResponseYou've already chosen the best response.0so now just the square root of 25?

Best ResponseYou've already chosen the best response.0yes! please remember we have two values since we can write this: (5)^2= 25 (+5)^2=25

Best ResponseYou've already chosen the best response.0so we can write: \[\Large r = \pm \sqrt {25} = \pm 5\]

Best ResponseYou've already chosen the best response.0if we take the square root of both sides, we get: \[\Large z + 7 = \pm \sqrt 3 \]

Best ResponseYou've already chosen the best response.0now, I subtract 7 at both sides, so I get: \[\Large z + 7  7 = \pm \sqrt 3  7\] please simplify

Michele_Laino

Best ResponseYou've already chosen the best response.0no, since at the right side we have not 73, the the simplified expression is: \[\Large z =  7 \pm \sqrt 3 \]

Best ResponseYou've already chosen the best response.0if we subtract 4 from both sides, I get: \[\Large {x^2}  12x + 36  4 = 4  4\] please simplify

Best ResponseYou've already chosen the best response.0what is 364=...?

Michele_Laino

Best ResponseYou've already chosen the best response.0after that simplification, we can write this: \[\Large {x^2}  12x + 32 = 0\]

Best ResponseYou've already chosen the best response.0now we have to solve that equation. Do you know how to solve that quadratic equation?

Best ResponseYou've already chosen the best response.0@Michele_Laino how do i?

Best ResponseYou've already chosen the best response.0then we have to apply another method

Best ResponseYou've already chosen the best response.0we have to search for 2 numbers, such that their sum is 12 and their product is 32

Michele_Laino

Best ResponseYou've already chosen the best response.0that's right! so the requested factorization is: \[\Large {x^2}  12x + 32 = \left( {x  8} \right)\left( {x  4} \right)\]

Michele_Laino

Best ResponseYou've already chosen the best response.0using the rule of the square of a binomial, we can write this: \[\Large {y^2} + 14y + 49 = {\left( {y + 7} \right)^2}\]

Michele_Laino

Best ResponseYou've already chosen the best response.0now: for what values for y, we have \[\Large {\left( {y + 7} \right)^2}=0\]

Best ResponseYou've already chosen the best response.0if y= 7, what is (y+7)^2=...

Michele_Laino

Best ResponseYou've already chosen the best response.0ok! so what is the requested value of y?

Michele_Laino
 one year ago
Best ResponseYou've already chosen the best response.0that value for y is y=7, since (7+7)^2=0 so what is the right option?

Michele_Laino
