4x2 = 8, 8-9 = -1 therefore the answer is "-1"
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
x2+7x-8 = (x-1(x+8)
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
x2+7x-8 = (x-1(x+8)
x(7x ^2 - 4x + 8)
4x2 = 8, 8-9 = -1 therefore the answer is "-1"
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
(7x + 8)(7x - 8)
4x2 + x2 = 8 + x2
x2+7x-8 = (x-1(x+8)
1x8 2x4 4x2 4x2
y=4x2+3x+8
8 because 4x2 is 8 and 4x4 is sixteen so if you subtract 8 from sixteen you get 8
x2+7x-8 = (x-1(x+8)
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
x2 + 7x - 8 = (x + 8)(x - 1)
