Please help me and explain how you got your answer!! don’t just give the answer pls

Step-by-step explanation:

2x^2 + 3x =9

when equation like a * (x^2)+ b*x  + c =0

solution like;

x= (-b +sqrt(b^2 - 4ac))/2a

and

x= (-b - sqrt(b^2 - 4ac))/2a

Now consider 2x^2 + 3x -9 =0

so a=2, b=3, c= (-9)

Let first consider  x= (-b + sqrt(b^2 - 4ac))/2a;

x= (-b + sqrt(b^2 - 4ac))/2a

x= ( -3  + sqrt( 3^2 - 4*2*(-9)) )/2 *2

  = 6/4

  = 1.5

Let second consider  x= (-b - sqrt(b^2 - 4ac))/2a;

x= (-b - sqrt(b^2 - 4ac))/2a

x= ( -3  - sqrt( 3^2 - 4*2*(-9)) )/2 *2

  = -12/4

  = -3

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.
