1. Factor. 100x^2−20xy+y^2

1 answer:

6 0

1. (10x-y)² (because 100x²=(10x)², and -20xy=-2(10x)*y)
2. (2x+7y)(2x-7y) (because 4x²=(2x)², 49y²=(7y)²)
3. -2x²+8x-10
4. -12x^5+14x³-2x²+10x (use distributive property, multiply every term in the parenthesis by -2x)

Using factoring, which values are the solutions to the quadratic equation 2m2+7m−30=0?

Luden [163]

Answer:

B: m = -6 or m = 5/2

Explanation:

$\rightarrow \sf 2m^2 +7m - 30 = 0$

breakdown

$\rightarrow \sf 2m^2 +12m -5m- 30 = 0$

take out common factor

$\rightarrow \sf 2m(m +6) -5(m+ 6) = 0$

collect into groups

$\rightarrow \sf (2m -5)(m+ 6) = 0$

set to zero

$\rightarrow \sf 2m -5=0, \ m+ 6 = 0$

change sides

$\rightarrow \sf m=2.5, \ m= -6$
