Write a quadratic equation in standard form that has two solutions, -5 and 7

Step-by-step explanation:

1) find two factors of c that sum up to -2.

2) 5 and -7 are factors of -35 that sum up to -2.

3) (x+5)(x-7)

4) x+5= 0, x= -5

5) x-7= 0, x= 7

4) the two solutions are -5 and 7.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

answer: 1, 3 and 5 are correct
