Question

Express this quadratic equation as the product of two binomials.

y = 4x^2 - 28x - 32

Answer 1

factorize it

Answer 2

y = 4(x^2 - 7x - 8 )

Answer 3

y=4(x+1)(x-8)

Answer 4

thankyou how do you do this one? Find the roots of the equation y = 4x^2 - 20x - 24 .

Answer 5

first factorize it
can you do that ?

Answer 6

No i don't k now how?

Answer 7

know*

Answer 8

\( y = 4x^2 - 20x - 24 . =4(x^2-5x-6)=4(x-6)(x+1)\)
nw
4(x-6)(x+1)=0
we have two cases
x-6=0 \(\rightarrow \) x=6
x+1=0 \(\rightarrow \) x=-1

Answer 9

So (-1.0) and (6,0) ?

Answer 10

yep ^

Answer 11

Okay i also need help on this one Find c such that x^2 - 24x + c is a perfect square trinomial.

Answer 12

well i feel tired nw
post it in new thread im sure someone else will help
good luck ^

Answer 13

OKay thankyou for your help(:
