Question

pls solve the part 1 of question 3​

Answer 1

Answer:

2x^2+3x=0-k

4x + 3x = 0-k

7x =-0

x =7 ÷0

ans 0

Answer 2

Step-by-step explanation:

iii) 2x^2 - 5x - k = 0

If b^2 - 4ac is less than zero the roots are not

real.

=> a = 2, b = 5, c = k

b^2 - 4ac < 0

5^2 - 4×2×k < 0

25 - 8k < 0

- 8k < -25

k > 25/8

or, k > 3.125
