Answer:
d)0 and 7 are solutions of the original equation.
Step-by-step explanation:
Let's solve your equation step-by-step.
w=√7w
Step 1: Flip the equation.
√7w=w
Step 2: Solve Square Root.
√7w=w
7w=w2(Square both sides)
7w=w2
7w−w2=w2−w2(Subtract w^2 from both sides)
−w2+7w=0
w(−w+7)=0(Factor left side of equation)
w=0 or −w+7=0(Set factors equal to 0)
w=0 or w=7
Check answers. (Plug them in to make sure they work.)
w=0(Works in original equation)
w=7(Works in original equation)

Answer:
(2x - 5) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x + 35
Step-by-step explanation:
Given:
2x - 5 and 3x2 + 5x - 7
Product of two values means multiplication of the two values
(2x - 5) (3x^2 + 5x - 7)
6x^3 + 10x^2 - 14x - 15x^2 - 25x + 35
Collect like terms
6x^3 + 10x^2 - 15x^2 - 14x - 25x + 35
Simplify
6x^3 - 5x^2 - 39x + 35
(2x - 5) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x + 35
Therefore product of 2x - 5 and 3x2 + 5x - 7 is 6x^3 - 5x^2 - 39x + 35
