Question

p(x) = 5x² + kx + 2 solve for k​

Answer 1

Answer:

answer is 1

If (x - a) is a factor of p(x) = 5x² - kx - 18, then p( a) = 0

OR

p(a) = 0, where a is zero of the equation (x - a)

[ p(x) = 5x² - kx - 18]

find the zero of (x-2)

⟹ (x - 2) = 0

⟹ x = 0 + 2

⟹ x = 2

p(2) = 5(2)² - k(2) - 18 = 0

= 5(4) - 2k - 18 = 0

= 20 - 18 - 2k = 0

= 2 - 2k = 0

= -2k = -2

= k = -2/-2

= k = 1

value of k is 1.
