One Zero Is Three Times the Other

CBSE Class 10 · Solve it one decision at a time. A wrong pick earns a nudge, never the answer.

Step 1 of 4

The problem

One zero of p(x)=2x2−16x+kp(x) = 2x^2 - 16x + k is three times the other. Find kk and both zeroes.

Step 1 · Your move

Call the zeroes α\alpha and 3α3\alpha. What does the sum of the zeroes give?

p(x)=2x2−16x+kp(x) = 2x^2 - 16x + k
zeroes α and 3α\text{zeroes } \alpha \text{ and } 3\alpha
