Well, she could do 30/10 which equals 3. So she could do 10 groups with 3 students in each group.

Multiply the polynomial by distribution. Show your work and explain the steps you used to solve.
balandron [24]

Hello,

Why "Multiply the polynomial by distribution"  ?

It's s t u p i d, you compliquate the equation.

In order to find the roots of P(a)=(a-3)(a²+2a-6)=0

a²+2a-6

=(a²+2a+1)-7

=(a+1)²-7

=(a-√7)(a+√7)

P(a)=(a-3)(a-√7)(a+√7)

Roots are 3,√7 and -√7

(If i have well understood the question , sorry if not)

one way is to factor the expressions

(a)

10^{5} (1.2 + (5.35 × 10^{1}))

= 10^{5} (1.2 + 53.5)

= 54.7 × 10^{5} = 5.47 × 10^{1}× 10^{5} = 5.47 × 10^{6}

(b)

10^{-3}((6.91 × 10^{1}) + 2.4)

= 10^{-3}(69.1 + 2.4)

= 71.5 × 10^{-3} = 7.15 × 10^{1} × 10^{-3} = 7.15 × 10^{-2}

(c)

10^{5}((9.7 × 10^{1}) + 8.3)

= 10^{5}(97 + 8.3)

= 105.3 × 10^{5} = 1.053 × 10^{2} × 10^{5} = 1.053 × 10^{7}

(d)

10^{1}((3.67 × 10^{1}) - 1.6)

= 10^{1}(36.7 - 1.6)

= 35.1 × 10^{1} = 3.51 × 10^{1} × 10^{1} = 3.51 × 10^{2}

(e)

10^{-6}((8.41 × 10^{1}) - 7.9)

= 10^{-6}(84.1 - 7.9 )

= 76.2 × 10^{-6} = 7.62 × 10^{1} × 10^{-6} = 7.62 × 10^{-5}

(f)

10^{4}((1.33 × 10^{1}) - 4.9 )

= 10^{4}(13.3 - 4.9) = 8.4 × 10^{4}
