Question

find product of (5x*2-2y+7)(4x-1)​

Answer 1

Step-by-step explanation:

3x and 7x

3x and 7x(ii) -5xy and 9xy

3x and 7x(ii) -5xy and 9xySolution:

3x and 7x(ii) -5xy and 9xySolution:We have

3x and 7x(ii) -5xy and 9xySolution:We have(i) 3x + 7x = (3 + 7) x = 10x

3x and 7x(ii) -5xy and 9xySolution:We have(i) 3x + 7x = (3 + 7) x = 10x(ii) -5xy + 9xy = (-5 + 9)xy = 4xy

do like this

Answer 2

Answer:

40x² - 8xy + 9x + 2y -7

Step-by-step explanation:

( 5x × 2 - 2y +7) ( 4x- 1)

(10x - 2y +7) ( 4x-1)

4x( 10x - 2y +7) -1 (10x - 2y +7)

40x² - 8xy + 28x - 19x + 2y -7

40x² - 8xy + 9x +2y - 7
