Question

Zero of the expression x²+x-6 is​

Answer 1

$\huge{\mathcal{\blue{\underline{Answer}}}}$

$= x {}^{2} + x - 6 \\ = x {}^{2} + 3x - 2x - 6 \\ = x(x + 3) - 2(x + 3)$

$\huge{\mathcal{\blue{\implies{\underline{(x+3)(x-2)}}}}}$

Answer 2

Answer:

x - 2 = 0

x = 2

p ( x ) = x^2 + x - 6

p ( 2 ) = ( 2 ) ^ 2 + 2 - 6

= 4 + 2 - 6

= 6 - 6

= 0
