Question

( 7x + 9y² ) ( 3xy ) find the following products and then evaluate when x is = 2 , Y = -1​

Answer 1

$\huge\underline\mathtt\red{Answer:}$

Step-by-step explanation:

$\fbox \color{black} Given:-$

• x= 2 , y= -1

$\huge\underline\mathtt\red{To find:}$

• Product of ( 7x + 9y² ) ( 3xy )

Solution:-

$(7 \times 2 + 9 \times - 1)(3 \times 2 \times - 9)$

$(14 +( - 9)( - 54)$

$(14 - 9)( - 54)$

$5 \times - 54$

$= - 270$

Answer 2

Answer:

x= 2 , y= -1

\huge\underline\mathtt\red{To find:}

Tofind:

Product of ( 7x + 9y² ) ( 3xy )

Solution:-

(7 \times 2 + 9 \times - 1)(3 \times 2 \times - 9)(7×2+9×−1)(3×2×−9)

(14 +( - 9)( - 54)(14+(−9)(−54)

(14 - 9)( - 54)(14−9)(−54)

5 \times - 545×−54

= - 270=−270
