If one zero of the quadratic polynomialf(x)=4xsquare-8kx-9 is negative of the other, find the value of k

Posted by Aman Kumar 5 years, 5 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 5 years, 5 months ago

Comparing f(x) = 4x² - 8kx - 9 with ax2+bx+c we get
a=4; b=-8k and c=-9.
Since one root is the negative of the other, let us assume that the roots are p an -p.
Sum of the roots, a+(-a)=-b/a= - (-8k) / 4
0=2k
k=0

Yogita Ingle 5 years, 5 months ago

27=51+3m(m-6)

27 = 51 + 3m₂- 18 m
3m² - 18 m + 51 -27
3m² - 18 m + 24 = 0
3m² - 12m - 6m + 24 = 0
3m ( m - 4) - 6 (m - 4) = 0
m - 4 = 0 or 3m - 6 = 0
m = 4 or m = 2
