Question

factorise: x²- 14x - 32​

Answer 1

Answer:

Take bro

Step-by-step explanation:

Please note that to make it a perfect square you need to add and subtract a numerical.

x² + 14 x = 32

The equation can also be written as

x² + 2 * 7 x = 32 (As the Standard form is a² +2ab + b² = 0)

Now adding 49 to both sides (As 49 is the square of other number 7)

x² + 14 x + 49 = 32 + 49

This can also be written as

(x + 7)² = 81

√(x + 7)² = √81

Taking Square roots of both sides

(x + 7) = ± 9

This means

Either (x + 7) = + 9 or (x + 7) = - 9

Therefore,

x = 9 – 7 or x = - 9 - 7

x = 2 or x = - 16

Answer 2

Answer:

${x}^{2} - 14x - 32 \\ {x}^{2} - 16x + 2x - 32 \\ x(x - 16) + 2(x - 16) \\ (x + 2)(x - 16)$
