Given equation is 2x²+x-28 = 0
⇛ 2x²+8x-7x-28 = 0
⇛ 2x(x+4)-7(x+4) = 0
⇛ (x+4)(2x-7) = 0
⇛ x+4 = 0 or 2x-7 = 0
⇛ x = -4 or 2x = 7
⇛x = -4 or x = 7/2.
Answer:
well then, what was right?
Step-by-step explanation:
The three terms are not like terms, so they cannot be added together.
The expression is simplified.
If you need to factor the expression, then the instructions should be factor the expression, not simplify.
Answer:
i think the answers are A, C and D
Step-by-step explanation:
The formula for point slope is:
y-y1=m(x-x1)
m is your slope: 3; plug in 4 for y1 and 2 for x1
y - 4=3(x-2)
