Answer:

(x-3)^2=2

Step-by-step explanation:

${x}^{2} - 6x + 7 = 0 \\ adding \: 2 \: both \: sides \\ {x}^{2} - 6x + 7 + 2 = 0 + 2 \\ {x}^{2} - 6x + 9 = 2 \\ {x}^{2} - 6x + {(3)}^{2} = 2 \\ (x - 3) ^{2} = 2$

Find the product of the expression:<br> (5p^3) (-1m^8p^2)

Rainbow [258]

Answer:

We conclude that:

$\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8$

Step-by-step explanation:

Given the expression

$\left(5p^3\right)\:\left(-1m^8p^2\right)$

Apply the rule:

$a\left(-b\right)=-ab$

so the expression becomes

$\left(5p^3\right)\left(-1\cdot \:m^8p^2\right)=-5p^3\cdot \:1\cdot \:m^8p^2$

Apply the rule:

$a^b\cdot \:a^c=a^{b+c}$

so the expression becomes

$=-5p^{3+2}\cdot \:1\cdot \:m^8$ ∵ $p^3p^2=p^{3+2}$

$=-5p^5\cdot \:1\cdot \:m^8$

$=-5p^5m^8$

Therefore, we conclude that:

$\left(5p^3\right)\:\left(-1m^8p^2\right)=-5p^5m^8$

Factorise using the difference of two squares:<br> I)4x squared-(2x+3) squared

alex41 [277]

4x² - (2x + 3)²
4x² - (2x + 3)(2x + 3)
4x² - (2x(2x + 3) + 3(2x + 3))
4x² - (2x(2x) + 2x(3) + 3(2x) + 3(3))
4x² - (4x² + 6x + 6x + 9)
4x² - (4x² + 12x + 9)
4x² - 4x² - 12x - 9
-12x - 9
-3(4x) - 3(3)
-3(4x + 3)
