Answer:
A
Step-by-step explanation:
Answer: -2x^2-12x-17
Step-by-step explanation:
-2(x+3)^2+1 Original equation
-2(x^2+3x+3x+9)+1 factor (x+3)(x+3)
-2x^2-12x-18+1 Multiply the factored part by -2
-2x^2-12x-17 Combine like terms
<span>A technique for mental multiplication is called factoring the tens which relies on the fact that 10*n, for any real number n. This will make the problems easy to compute. 6 x 2 = 12 is a memory value. </span>
12 x 10 = 120
12 X 100 = 1200
Take for instance in 6 x 2, 6 x 20 and 6 x 200. Find the factors and these are the computations. We can also say:
<span>6 x 20 = 6 x 2 x 10 = 12 x 10 = 120
60 x 20 = 6 x 10 x 2 x 10 = 12 x 10 x 10 = 1200</span>
It must be remembered that in the commutative and associative properties of multiplication, the order of the factors does not matter when solving this kind of problem
