Question

factorise: 2x²+3x-90​

Answer 1

Answer:

Step-by-step explanation:

=2x²+15x-12x-90 [°.° 15*12=180 & 15-12=3]

=x(2x+15)-6(2x+15) (Taking x common in first two terms and (-6) from last two terms)

=(2x+15)(x-6) [Taking (2x+15) froms both terms]

Answer 2

hey there

hope my answer helps you

2x² + 3x - 90 = 0

as it is a quadratic equation

2 * -90 = -180

15 * - 12 = -180

15 - 12 = 3

2x² - 12x + 15x - 90 = 0

2x ( x - 6 ) + 15 ( x -  6 )

( x - 6 ) ( 2x + 15 ) are the factors

hope my answer helps you
