Construct quadratic equation whose root are -3,+5.show the sloving

x² - 2x - 15 = 0

Step-by-step explanation:

Given that the roots are x = - 3 and x = 5

Then the factors are (x + 3) and (x - 5)

The equation is then the product of the factors

(x + 3)(x - 5) = 0 ← expand left side using FOIL

x² - 5x + 3x - 15 = 0, that is

x² - 2x - 15 = 0

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
