Question

if p(x) =kx2+4x+26 p(1)=7 then k=​

Answer 1

Step-by-step explanation:

your ans is 26 becoz the x =32

Answer 2

${ \large{ \pmb{ \sf{★Given... }}}}$

p(x) = kx² + 4x + 26 p(1) = 7

${ \large{ \pmb{ \sf{★To \: Find... }}}}$

Value of k..?

${ \large{ \pmb{ \sf{★Solution... }}}}$

• We have to substitute 1 in place of x and taking equal to as 7 . Thus, we can find value of K

${ \implies{ \sf{p(x) = k {x}^{2} + 4x + 26 }}}$

$\: { \implies{ \sf{p(1) = k {(1)}^{2} + 4(1) + 26 = 7 }}}$

$\: { \implies{ \sf{k + 4 + 26 = 7}}}$

$\: { \implies{ \sf{k + 30 = 7}}}$

$\: { \implies{ \sf{k = 7 - 30}}}$

$\: { \implies{ \sf{k = - 23}}}$

${ \large{ \pmb{ \sf{★ Final \: Answer... }}}}$

Value of k is -23
