Question

(i) If the product of the two roots of the equation x2-3x+k=10 is -2, then the value of k is ​

Answer 1

Answer:

Step-by-step explanation:

equired equation :     \frac{1}{7\\} k x k = 7

\frac{1}{7} \\ k^{2} = 7

taking \frac{1}{7} to right side of the equation

k^{2} = 7 x 7      (reciprocal of \frac{1}{7})

k^{2} = 49

k = \sqrt{49}
