Question

How can I Factor X^2+x-2

Answer 1

The factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).

What is the factored form of the given expression?

Given the expression;

x² + x - 2

Consider the standard form ax² + bx + c compared to the given expression;

• a = 1
• b = 1
• c = -2

Now, we find a pair of integers whose product gives the value of c which is -2 and whose sum gives the value of b which is 1.

The integers are -1 and +2.

Check

-1 × 2 = -2

-1 + 2 = 1

Now, we write the factored form using these integers.

( x - 1 )( x + 2 )

Therefore, the factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).
