35x + 26x - xsquare = 60,

35x + 26x - xsquare = 60,

35x + 26x - xsquare = 60
X square - 61x + 60 = 0
(x-1)(x-60)=0
X = 1 or x = 60

Solve the following inequality 3x-90 4x squared + 2x + 1

3x-9

The solution of 7x square + 26x + 19 = 0

7x²+7x+19x+19=0
7x(x+1)+19(x+1)=0
(x+1)(7x+19)=0
x=-1,x=-19/7

-4x+16-26x

x=0 x=√10/2-2 x=√10/2+2

Factorization factor (1) 2x ^ 2-2x-1 (2) 2x ^ 3-7x ^ 2 + 2x + 3

⑴2x^2-2x-1
=2[x-(1-√3)/2][x-(1+√3)/2]
⑵2x^3-7x^2+2x+3
=2x³-2x²-5x²+5x-3x+3
=2x²(x-1)-5x(x-1)-3(x-1)
=(x-1)(2x²-5x-3)
=(x-1)(x-3)(2x+1)

Factorize 2x ^ 2-7x + 3
Why is there a negative number when a cross meets

2 - 11 - 32x ^ 2-7x + 3 = (2x-1) (x-3) the negative number is determined according to the coefficient of the first term. For this problem, the coefficient of the first term is - 7. If no negative sign is added, the cross will be multiplied by 7, so the negative sign will be added before 1 and 3

If a * b = a (ab-3) is defined, then the solution of the equation (- 2) * x = 8 is?

∵a*b=a(ab-3)
∴(-2)*x=(-2)[(-2)x-3]=8
4x+6=8
x=1/2

If a & B = a (ab-3) is defined, then the equation (- 2) & x = 8

(-2)&x=8
The results show that: - 2 (- 2x-3) = 8
4x+6=8
4x=8-6
4x=2
x=0.5

Define a new operation * so that a * b = AB (a + b), then what is the following of the equation (x * 2) * 2 = 96

X * 2 = 2x (x + 2) = 2x ^ 2 + 4x left = (x * 2) * 2 = (2x ^ 2 + 4x) * 2 = 2 (2x ^ 2 + 4x) (2x ^ 2 + 4x + 2) = 96, so (2x ^ 2 + 4x) (2x ^ 2 + 4x + 2) = 48, that is, (2x ^ 2 + 4x) ^ 2 + 2 (2x ^ 2 + 4x) - 48 = 0 (treat (x ^ 2 + 4x) as a whole) (2x ^ 2 + 4x-6) (2x ^ 2 + 4x + 8) = 0x ^ 2 + 2x

Definition operation: a * b = a (AB + 7), then the solution of equation 3 * x = 2 * (- 8) is______ ．

According to the meaning of the title, 3 (3x + 7) = 2 [2 × (- 8) + 7], 9x + 21 = - 18, 9x = - 39, and 13X = - 133
