Quadratic formula where:
do both do get the roots of the equation
Answer:
10x2 + 2x + 13.
Step-by-step explanation:
10x2 + 3 - (-2x - 10) (Note you have to put the -2x - 10 in brackets).
= 10x2 + 3 + 2x + 10 (Distributing the negative over the brackets).
= 10x2 + 2x + 13.
18/45 can be divided by nine, so it would be 2/5
Answer:
1 1/12
Step-by-step explanation:
You need to find a common denominator that fits both 1/4 and 5/6. We know that 12 fits both, so we multiply each to get it, for example:
1/4 = 3/12
5/6 = 10/12
Now we say 3/12 + 10/12 = 13/12 and simplify to get 1 1/12
4(2x +5) = (8x + 20)
8x =20 is an equivalent expression
