How do you solve this?
x²+19x= -88
Show step by step please :)
x²+19x= -88
Show step by step please :)
-
x^2 + 19x = -88
x^2 + 19x + 88 = 0
find factors of 88 that will add up to 19.
in this case, 11 & 8
(x + 11)(x + 8) = 0
equate each to 0 and solve for x
x + 11 = 0
x = -11
x + 8 = 0
x = -8
x = -11 and -8
x^2 + 19x + 88 = 0
find factors of 88 that will add up to 19.
in this case, 11 & 8
(x + 11)(x + 8) = 0
equate each to 0 and solve for x
x + 11 = 0
x = -11
x + 8 = 0
x = -8
x = -11 and -8

How do you solve this 8th grade Algebra Regents problem? x²+19x=-88?
--------------------------------------…
rearrange the eq to x^2 + 19x + 88 = 0
notice that the factors of 88 are 11 and 8.
notice that if you add these factors, you get + 19,
which is the coefficient of the x-term.
The factors are: (x+11)(x+8) = 0, which means
the roots are -8 and -11.

-
x^2 + 19x = -88
x^2 + 19x + 88 =0
(x+8)(x+11)
As 11+8=11 and 11*8=88
x^2 + 19x + 88 =0
(x+8)(x+11)
As 11+8=11 and 11*8=88
