Question

find the value k if x^2 + kx + 6 = (x+2) (x+3) ​

Answer 1

X^2+kx+6=(x+2)(x+3)

X^2+kx+6=x^2+3x+2x+6

X^2+kx+6=x^2+5x+6. { X^2 will be cansaled}

Kx+6=5x+6. { 6 will be cansaled}

Kx=5x

K=5

Answer 2

Answer is here :

x²+ kx + 6 = ( x + 2 ) ( x + 3 )

so

x² + kx +6 = (x + 2 ) ( x + 3 )

x² + kx + 6 = x² + 3x + 2x + 6

x² - x² + kx = 3x + 2x + 6 - 6

kx = 5x

k = 5x / x

k = 5

I hope this point is clear .
