For 2x2— 5x —3 = 0, determine which of the following are solutions?(i) x = 3 (ii) x= –2(iii)  (iv)

The two possible solutions are x = 3 and .

Since this question is given in standard form, meaning that it follows the form: ax² + by + c = 0, we can use the quadratic formula to solve for x:

x = 3

That value of x is correct as well!

Therefore, the two possible solutions are:

x=3

x=−0.50

For 2x²— 5x —3 = 0, determine which of the following are solutions?
(i) x = 3 (ii) x= –2

(iii) (iv)
