Question

Find the value of k, if (x-1) is a factor of p(x)= 4x2 +3x2 - 4x+k

Answer 1

Answer:-3

Step-by-step explanation:ok first it is given that (x-1) is a factor of 4x^2+3x^2-4x+I

Then x-1=0

×=1 put this value in this equation

$4 {x}^{2} + 3 {x}^{2} - 4x + k$

Let's first find the zero of the polynomial :-

$(x - 1) = 0 \\ (x) = 1$

So, value of p(x) is 1

Step-by-step explanation:

$Substitute \: the \: Number \: in \: the \: equation - \\ p(1) = 4 ({1}^{2}) + 3( {1}^{2} ) - 4(1) + k \\ \: \: \: \: \: \: \: \: = 4 + 3 - 4 + k \\ \: \: \: \: k = - 3$

• :. Value of k is -3
