Answer:
what does it mean by equation
Answer:
Step-by-step explanation:
We have to use the law of indices for finding the equivalent expression.
We square 8, which is 64 and multiply the two powers.
We multiply the 2 powers giving us, , which simplifies to 2.
× = This is the answer as we multiply the two indices together.
I hope this helps!! ^-^
Factor out 4
4(x^2 + 2x - 15)
to factor the equation inside the parenthesis, find two numbers that multiply to -15 and add to 2
those numbers are: 5 and -3
the answer is: 4(x+5)(x-3)
