Question

Factorise

${x}^{2} + 250x - 750000$
Find x​

Answer 1

Explanation:

Hey mate,

Answer:-

$x = - 1000 \: \: and \: x = 750$

Explanation

${x}^{2} + 250 - 750000$

Using. Middle term split method

${x}^{2} + 750x \: - 1000x - 750000 = 0$

Taking common

$x(x - 75 0) + 1000(x - 750) = 0$

$therefore \\ \\ x = - 1000 \: and \: x = 750$

$x + 1000 = 0 \: or \: x - 750 = 0$

Answer 2

FACTORISING---

x2+250x–750000

x2 - 750x + 1000x - 750000

x(x–750)+1000(x–750)

(x+1000)(x–750)

x=–1000,750
