use the zero product property to find the solutions to the equation x² + x - 30 = 12.
x = -7 or x = 6
x= -7 or x = -6
x = -6 or x = 7
ox= 6 or x = 7

x =  -6, or x = 7 is the ONLY correct solution of the given equation  

Step-by-step explanation:

Here, the given expression is

or the standard form of the above expression is

or,

Now, if the equation is of the form

Then, b = SUM OF THE ROOTS

and c = PRODUCT OF THE ROOTS

Similarly, in the above expression:

       b = 1 = Sum of roots

and c = -42 = Product of the roots.

Here, for x =  -6, or x = 7:

Sum of Roots = -6 + 7 = 1

Product of roots =  (-6)(7) =  -42

Hence, x =  -6, or x = 7  is the ONLY correct solution of the given equation.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
