Let p(x) = ax³ + 4x² + 3x - 4 and q(x) = x³ - 4x + a be the given polynomials. The remainders when p(x) and q(x) are divided by (x - 3) are p(3) and q(3) respectively.
By the given condition, we have
p(3) = q(3)
{tex}\Rightarrow{/tex} a {tex}\times{/tex}3³ + 4 {tex}\times{/tex}3² + 3 {tex}\times{/tex}3 - 4 = 3³ - 4 {tex}\times{/tex}3 + a
{tex}\Rightarrow{/tex} 27a + 36 + 9 - 4 = 27 - 12 + a
{tex}\Rightarrow{/tex} 26a + 26 = 0 {tex}\Rightarrow{/tex} 26a = -26 {tex}\Rightarrow{/tex} a = -1

Let N = 5q + 1
{tex}\therefore{/tex} N² = (5q + 1)²
{tex}\Rightarrow{/tex} N²= 25q² + 10q + 1
N²= 5(5q² + 2q) + 1
= 5m + 1, where q is soqe integer
Hence, the square of any positive integer of the form 5m + 1 will leave a remainder 1 when divided by 5 for some integer m .

117 = 13 {tex}\times{/tex} 3 {tex}\times{/tex} 3
65 = 13 {tex}\times{/tex} 5
HCF (117, 65) = 13
LCM(117,65) = 13 {tex}\times{/tex} 5 {tex}\times{/tex} 3 {tex}\times{/tex} 3 = 585

Here is given that:
{tex}HCF =65m-117{/tex}

{tex}13=65m-117{/tex}

{tex}65m=130{/tex}
m = {tex}\frac { 130 } { 6 5 } ={/tex}2

Sia ? 6 years, 4 months ago

We have, x = 4 and x = -3.
Then,
x - 4 = 0 and x + 3 = 0
{tex}\Rightarrow{/tex} (x - 4)(x + 3) = 0
{tex}\Rightarrow{/tex} x² + 3x - 4x - 12 = 0
{tex}\Rightarrow{/tex} x² - x - 12 = 0

This is the required quadratic equation

Sia ? 6 years, 4 months ago

sin(135)
= sin (90 + 45) // sin(a + b) = sin(a)cos(b) + cos(a)sin(b)
= sin(90)cos(45) + cos(90)sin(45)
= ( 1 x 1/√2) + (0 x 1/√2)
= 1/√2
= (√2)/2

Zeros are -2 and -1. Thus ( x-2)=0, (x -1)=0 We get (x+2)and (x+1) Multiply both, we get X square + 3x + 2, now divide it with f(x) We get 2x square -5x - 3,now factorise it ,we get (x -3) (2x+1) (X-3)=0, (2x+1)=0, Solve it, we get X=3 and x= -1/2
