x^2−10x+27=0

Step 1: Use quadratic formula with a=1, b=-10, c=27.

−b±√b2−4ac/2a

x= −(−10)±√(−10)2−4(1)(27) /2(1)

10±√−8 /2

Answer:

No real solutions.

$(a-b)^2=a^2-2ab+b^2$

$x^2-10x+27=0\ \ \ \ |-27\\\\x^2-10x=-27\\\\x^2-2\cdot x\cdot5+27=0\ \ \ |+5^2=25\\\\x^2-10x+25=-27+25$

a^2 + b^2 = c^2
3^2 + 10^2 = c^2
109 = c^2

Answer:

c. $2a^3x^4-3a^3x^3+a^4x^2$

d. $63x^5y^3-30x^2y^4-7x^3y^2$

Step-by-step explanation:

For this exercise you need to remember the following:

1. The multiplication of signs:

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

2. The Product of powers property, which states that:

$(a^m)(a^n)=a^{(m+n)}$

3. The Distributive property:

$a(b\±c)=ab\±ac$

Knowing that, you can solve the multiplication of the polynomials:

c. $(-2ax^2+3ax-a^2)(-a^2x^2)=\\\\=(-2ax^2)(-a^2x^2)+(3ax)(-a^2x^2)+(-a^2)(-a^2x^2)=2a^3x^4-3a^3x^3+a^4x^2$

d. $(6.3x^3y-3y^2-0.7x)(10x^2y^2)=\\\\=(6.3x^3y)(10x^2y^2)+(-3y^2)(10x^2y^2)+(-0.7x)(10x^2y^2)=63x^5y^3-30x^2y^4-7x^3y^2$
