Question

1)y=2x^2-12x+14 in vertex form with steps asap please

Answer 1

Answer:

y = 2 ( x + 3 ) 2 − 4

Step-by-step explanation:

Use the form a x 2 + b x + c , to find the values of a , b , and c . a = 2 , b = 12 , c = 14 Consider the vertex form of a parabola. a ( x + d ) 2 + e Substitute the values of a and b into the formula d = b 2 a . d = 12 2 ( 2 ) Simplify the right side. d = 3 Find the value of e using the formula e = c − b 2 4 a . e = − 4 Substitute the values of a , d , and e into the vertex form a ( x + d ) 2 + e . 2 ( x + 3 ) 2 − 4 Set y equal to the new right side. y = 2 ( x + 3 ) 2 − 4
