The quadratic polynomial p(x) with –24 and 4 as a product and one of the zeros respectively is
Answers
Given: Product of roots= -24 and 4 is one of the roots
To find: Quadratic polynomial p(x)
Solution:
Product of roots=-24
One root=4
Therefore the other root must be -24/4=-6
Sum of roots=4+(-6)=-2
Product of roots=-24
Now, we know that quadratic polynomial p(x) is given by =x^2- (sum of roots)x + Product of roots
Therefore,the equation is given by x^2+2x-24
Given : The quadratic polynomial p(x) with –24 and 4 as a product and one of the zeros respectively
To Find : Polynomial
Solution:
Product of zeroes = -24
One zero = 4
Hence other zero = -24/4 = - 6
p(x) = ( x - a)(x - b)
where a nd b are zeroes
p(x) = (x -4)(x - (-6))
= ( x - 4)(x + 6)
= x² + 2x - 24
p(x) = x² + 2x - 24
