8+—3(6+—6a) help please

LenKa [72]

We know that:

$(+)+(-)=(-)$

and:

$(-)*(+)=(-)$

$8+(-3)[6+(-6a)]=8+(-3)*6+(-3)*(-6a)=8-18+18a$ $=(-10)+18a$

if you have solve for $a$ then:

$(-10)+18a=0$
$18a=10$
$a= \frac{10}{18}$
$a=\frac{5}{9}$

How to factor <br> 49y^{2}-9x^{2}

lorasvet [3.4K]

Answer:

(7y + 3x)(7y - 3x)

Step-by-step explanation:

a² - b² = (a + b)(a - b)

49y² - 9x² = (7y)² - (3x)² {a = 7y ; b - 3x}

= (7y + 3x)(7y - 3x)
