Question

factorise 2x² +7x -15​

Answer 1

Answer:

Your answer is

Final result :

(2x - 3) • (x + 5)

Step-by-step explanation:

STEP

1

:

Equation at the end of step 1

(2x2 + 7x) - 15

STEP

2

:

Trying to factor by splitting the middle term

2.1 Factoring 2x2+7x-15

= 2x2 - 3x + 10x - 15

= x • (2x-3)

= (x+5) • (2x-3)

Which is the desired factorization.

Answer 2

$= 2 {x}^{2} + 7x - 15$

$= 2 {x}^{2} + (10 - 3)x - 15$

$= 2 {x}^{2} + 10x - 3x - 15$

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

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