7=-1^2+5(1)+c

7 = - 1^{2} + 5 (1) + c

c = 3

Solution steps

7 = - 1^{2} + 5 (1) + c

Switch sides

- 1^{2} + 5 (1) + c = 7

Apply rule

1^{a} = 1

1^{2} = 1

- 1 + 5 \cdot 1 + c = 7

Multiply the numbers:

5 \cdot 1 = 5

- 1 + 5 + c = 7

Add/Subtract the numbers:

- 1 + 5 = 4

c + 4 = 7

Move

4

to the right side

c = 3

x - 2 < 4

4 x - 5 < 11

m^{2} - m - 132

(x - 4) (x - 3) (x + 10) > 0
