Question

solve the following quadratic equation by factorisation ​

Answer 1

$\huge\blue{solution}$

m^2 - m - 2 = 0

m^2 -(2-1)m - 2 = 0

m^2 - 2m + 1m - 2 = 0

m(m-2)+1(m-2)

(m-2)(m+1)

m = -2,1

0ption d

hope it helps you

Answer 2

Solution ==》

Answer ==》

☆Given =》

▪︎ m²-m-2=0

☆ To find =》

Solve Quadratic equation

☆ Explanation ==》

m²-m -2=0

m²-(2-1)m-2=0

m²-2m+1m-2=0

m(m-2)+1(m-2)

(m-2)(m+1)=0

m=2, m=-1

So, option c is correct....!!!
