Question

3. Fcatorise: (i) 6x^2 + 7x – 3 (ii) 2y^2 – 7^y – 15. Please required usgently freinds..

Answer 1

Heya ✌✌
Here is u r Ans ➡

✨ 1) ➡

$= 6x {}^{2} + 7x - 3$

$= 6x {}^{2} + 9x - 2x - 3$

$= 3x \times (2x + 3) - (2x + 3)$

$= (2x + 3)(3x - 1)$

✨2) ➡

$= 2y {}^{2} - 7y - 15$

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

$= y \times (2y + 3) - 10y - 15$

$= y \times (2y + 3) - 5(2y + 3)$

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

Q .Factorise

(x3 + 7x2 + 7x -15 )

= x × 3 + 7x × 2 + 7x -15

= x × 3 + 21x -15

= 3(x + 7x -5 )

= 3(8x - 5 )

Hope This Helps u ☺.

Answer 2

Given :-

(i) 6x^2 + 7x - 3

(ii) 2y^2 - 7y - 15

To find :-

Factors of (i) & (ii)

Solution :-

(i)

$6 {x}^{2} + 7x - 3 \\ = 6 {x}^{2} + 9x - 2x - 3 \\ = 3x(2x + 3) - 1(2x + 3) \\ = (2x + 3)(3x - 1)$

(ii)

$2 {y}^{2} - 7y - 15 \\ = 2 {y}^{2} - 10y + 3y - 15 \\ = 2y(y - 5) \: 3(y - 5) \\ = (y - 5)(2y + 3)$

Ans. :-

(i) 6x^2 - 6x - 3 ==> (2x + 3) (3x - 1)

(ii) 2y^2 - 7y - 15 ==> (y - 5) (2y + 3)

Hope it helps.
