Question

32 xsq - 18y sq factorize it

Answer 1

Answer:

Let's rewrite this expression as: x2 -8x -9

The middle term needs to be split into two terms whose product is -9x2 while the sum remains -8x

x2 - 9x + 1x -9

= x(x - 9) + 1 (x - 9)

= (x - 9) (x + 1)

Example 2: Factorize the quadratic expression: x2 +13x -168

Let's rewrite this expression as: x2 +13x -168

The middle term needs to be split into two terms whose product is -168x2 while the sum remains +13x

x2 + 21x - 8x -168

= x(x + 21) - 8 (x + 21)

= (x + 21) (x - 8)

Example 3: Factorize the quadratic expression: x2 +3x -40

Let's rewrite this expression as: x2 +3x -40

The middle term needs to be split into two terms whose product is -40x2 while the sum remains +3x

x2 + 8x - 5x -40

= x(x + 8) - 5 (x + 8)

= (x + 8) (x - 5)
