Answer:
A=5
Step-by-step explanation:
Hence the value of a and b are 5
Answer:
Since that is a quadratic equation, it will have 2 "x" intercepts.
x^2+7x+2
a = 1 b = 7 c = 2
You would solve for "x" using the quadratic formula.
x = [ -b +- sq root (b ^ 2 - 4 a c) ] / 2 a
x = [ -7 +- sq root (7^2 - 4*1*2) ] / 2 * 1
x = [ -7 +- sq root (49 -8) ] / 2
x1 = [-7 + 6.4031242] / 2
x1 = -.29844
x2 = [-7 - 6.4031242] / 2
x2 = -6.7016
