Re: 10 second questions

Hi bobbym and Howardroark,

The solutions to bobbym and Howardroark are correct. However, the question 2625 (bobbym) was regarding the nature of roots. Brilliant!

#2627. One root of the equation x[sup]2[/sup] - 3x + q = 0 is twice the other, then what is q?

#2628. The sum and products of the roots of 2x[sup]2[/sup] - 4x + 1 = 0 are ___________________________.

Re: 10 second questions

Hi bobbym and Howardroark,

The solutions to 2627 and 2628 are correct. The minor defect in the solution 2628 of Howardroark is 2 should replace -2 in the sum.

#2629. What is one root of 2x[sup]2[/sup] = 3x?

#2630. What is one factor of x[sup]3[/sup] - 2x[sup]2[/sup] - 5x + 6?

Re: 10 second questions

Hi bobbym and Howardroark,

New Year wishes to you too!

The solution to 2631 is correct given by bobbym. Well done!

Regarding 2632, the given equation is ax[sup]2[/sup] + bx +  = 0. That is my mistake, regretted.

#2633.

= _________________________.

#2634. The sum of two numbers is 9 and sum of their reciproals is

. What are the numbers?

Regarding 2631:
I took the partial fractions in the form

which shouldn't be used in this case.. There i went wrong..
