Whats the analysis of yieldsof 2x square+9x+10

The roots of the equation are -2.5 and -2

Step-by-step explanation:

We are given a quadratic equation and we are supposed to find the roots of the equation.

y =

To find the roots put y= 0.

We can factorize the given equation to get the roots.

= 0

2x ( x + 2 ) + 5 ( x + 2 ) = 0

( 2x + 5 )( x + 2 ) = 0

x = -  and  x = -2

Hence the roots of the quadratic equation are -2.5 and -2.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
