Question

Factorise. this 2x² - 7x -15. please give answer it's urgent.

Answer 1

Hey there !

2x² - 7x -15 = 0

2x² - 10x + 3x - 15 = 0

Taking common term out ,

2x [ x - 5 ] + 3 [ x - 5 ] = 0

[ 2x + 3 ] [ x - 5 ] -----> Factorized form

Answer 2

Answer:

$x=\frac{-3}{2},5$

Step-by-step explanation:

Given: $2x^2-7x-15=0$

To Find: Factorize

Solution:

$2x^2-7x-15=0$

$2x^2-10x+3x-15=0$

$2x(x-5)+3(x-5)=0$

$(2x+3)(x-5)=0$

$x=\frac{-3}{2},5$

Hence the $2x^2-7x-15=0$ =$(2x+3)(x-5)=0$=$x=\frac{-3}{2},5$
